Update MPFR to version 3.0.1 patch level 3.
Patch 3 fixes the following bug:
The mpfr_atan function calls mpfr_check_range on the unrounded
result (no longer allocated) instead of the rounded result.
Consequence of this bug: possible incorrect or invalid result and/or
incorrect flags if the unrounded result or rounded result is not in
the current exponent range. Or possibly worse if the memory used by
the unrounded result is modified before the return of the function.
This bug has been present since MPFR 2.1.0 (exceptions were not
supported before).
Patch 2 fixes the following bug:
The mpfr_rec_sqrt function can have undefined behavior due to the
call of mpn_add_1 or mpn_sub_1 (from GMP) with a null size, which is
not allowed. The fourth argument of mpn_add_1 or mpn_sub_1 (i.e. the
value that should have been added or subtracted) is here also 0, so
that the consequences are limited. In practice, with the current GMP
version, this yields a small buffer overflow (1 limb, i.e. 32 bits
or 64 bits), as shown by valgrind, with the possible consequences:
a crash, or memory corruption (very unlikely) if another process or
thread modifies the limb at the same time (as in this context, the
value is first read then written back by GMP). This bug has always
been present since the introduction of the mpfr_rec_sqrt function
in MPFR 2.4.0.
Patch 1 fixes the following bug:
If the exponent range has been reduced such that emax = 1 or 2,
mpfr_asin may give an incorrect result on +1 and -1.
which should probably never occur in practical codes.
