their time compiling, and 50% spinning in shell scripts. If you'd rather
spend your power bill on useful gcc cycles though, you might desire to use a
different shell for running build scripts - like pdksh, which is conveniently
available at bootstrap time.
But what if pdksh does this to you?
pdksh -c 'f=`pdksh -c set | wc -l`; f=$((f+1)); while ((f < 100000)); do f=$((f+1)); eval "v_${f}=0"; echo "$f"; done'|tail -1
13106
segmentation fault (core dumped) pdksh -c
Well that's annoying, isn't it.
% echo $(((13106*10+7)/8))
16383
... that's a magical number. Coincidence? Well, no.
tp->nfree = 8*nsize/10; /* table can get 80% full */
This particularly ugly overflow happens because tp->size is a short. When
texpand() does:
p = &ntblp[hash(tblp->name) & (tp->size-1)];
tp->size-1 will, given enough variables (80% of 2^15), type coerce into a
sign-extended 32-bit value of:
info registers $ecx
ecx 0xffff7fff -32769
That hash() function does more or less what you guess, it's a 32 bit unsigned
value. The chances of the final pointer pointing inside the valid allocated
block of memory are very low indeed.
The least-change solution is to change tp->size to a 32 bit value. I've left
it signed because that matches, for example, the size parameter passed to
texpand(). But really this code would be more correct with a liberal
sprinkling of "unsigned", and perhaps a bit of "size_t".
This change allows ffmpeg's configure script, as interpreted by pdksh, to
produce more usable output than a core file.
Bump PKGREVISION for code change.

OmniOS is an Illumos distro which falls under the SunOS variant for us.
Include mk/bsd.prefs.mk before the shells/tcsh/Makefile so the
OS_VARIANT variable is available for testing.

zsh-5.1/NEWS:
Changes from 5.0.8 to 5.1
-------------------------
The builtins declare, export, local, readonly and typeset
now have corresponding reserved words. When used in
this form, the builtin syntax is extended so that assignments
following the reserved word are treated similarly to
assignments that appear at the start of the command line.
For example,
local scalar=`echo one word` array=(several words)
creates a local "scalar" containing the text "one word"
and an array "array" containing the words "several"
"words".
- The print builtin has new options -x and -X to expand tabs.
- Several new command completions and numerous updates to others.
- Options to "fc" to segregate internal and shared history.
- All emulations including "sh" use multibyte by default; several
repairs to multibyte handling.
- ZLE supports "bracketed paste" mode to avoid interpreting pasted
newlines as accept-line. Pastes can be highlighted for visibility
and to make it more obvious whether accept-line has occurred.
- Improved (though still not perfect) POSIX compatibility for getopts
builtin when POSIX_BUILTINS is set.
- New setopt APPEND_CREATE for POSIX-compatible NO_CLOBBER behavior.
- Completion of date values now displays in a calendar format when
the complist module is available. Controllable by zstyle.
- New parameter UNDO_LIMIT_NO for more control over ZLE undo repeat.
- Several repairs/improvements to the contributed narrow-to-region
ZLE function.
- Many changes to child-process and signal handling to eliminate race
conditions and avoid deadlocks on descriptor and memory management.
- New builtin sysopen in zsh/system module for detailed control of
file descriptor modes.
zsh-5.1/README:
Incompatibilites between 5.0.8 and 5.1
--------------------------------------
The default behaviour when text is pasted into an X Windows terminal has
changed significantly (unless you are using a very old terminal emulator
that doesn't support this mode). Now, the new "bracketed paste mode"
treats all the pasted text as literal characters. This means, in
particular, that a newline is simply inserted as a visible newline; you
need to hit Return on the keyboard to execute the pasted text in one go.
See the description of zle_bracketed_paste in the zshparams manual for
more. "unset zle_bracketed_paste" restores the previous behaviour.
As noted in NEWS, the builtins declare, export, float, integer, local,
readonly and typeset now have corresponding reserved words that provide
true assignment semantics instead of an approximation by means of normal
command line arguments. It is hoped that this additional consistency
provides a more natural interface. However, compatbility with older
versions of zsh can be obtained by turning off the reserved word
interface, exposing the builtin interface:
disable -r declare export float integer local readonly typeset
This is also necessary in the unusual eventuality that the builtins are
to be overridden by shell functions, since reserved words take
precedence over functions.

Changelog:
Changes from 5.0.7 to 5.0.8
---------------------------
- Global aliases can be created for syntactic tokens such as command
separators (";", "&", "|", "&&", "||"), redirection operators, etc.
Use at your own risk! The POSIX_ALIASES option is interpreted more
strictly to prevent expansion of these and other alias names containing
quotes, glob metacharacters, parameter references, etc.
- There have been various further improvements to builtin handling
with the POSIX_BUILTINS option (off by default) for compatibility with
the POSIX standard.
- 'whence -v' is now more informative, and 'whence -S' shows you
how a full chain of symbolic links resolves to a command.
- The 'p' parameter flag now allows an argument to be specified
as a reference to a variable, e.g. ${(ps.$sep.)foo} to split $foo
on a string given by $sep.
- The option FORCE_FLOAT now forces variables, not just constants,
to floating point in arithmetic expressions.
- The type of an assignment in arithmetic expressions, e.g. the
type seen by the variable res in $(( res = a = b )), is now
more logical and C-like.
- The default binding of 'u' in vi command mode has changed to undo
multiple changes when invoked repeatedly. '^R' is now bound to redo
changes. To revert to toggling of the last edit use:
bindkey -a u vi-undo-change
- Compatibility with Vim has been improved for vi editing mode. Most
notably, Vim style text objects are supported and the region can be
manipulated with vi commands in the same manner as Vim's visual mode.
- Elements of the watch variable may now be patterns.
- The logic for retrying history locking has been improved.
- Some rationalisations have been made to the zsh/db/gdbm module that
should make it more useful and predictable in operation.

5.0.7
This is version 5.0.7 of the shell. This is a stable release.
There are minor new features as well as bug fixes since 5.0.6.
Note in particular there is a security fix to disallow evaluation
of the initial values of integer variables imported from the
environment (they are instead treated as literal numbers). That
could allow local privilege escalation, under some specific and
atypical conditions where zsh is being invoked in privilege elevation
contexts when the environment has not been properly sanitized, such
as when zsh is invoked by sudo on systems where "env_reset" has
been disabled.
5.0.6
This is version 5.0.6 of the shell. This is a stable release.
