$NetBSD: patch-ce,v 1.3 2002/10/15 10:47:00 agc Exp $
Robert Elz's PR 18664 contains the rationale for this patch:
A bug report (from Scott Lipcon) was submitted elsewhere:
http://savannah.nongnu.org/bugs/?func=detailbug&bug_id=1393&group_id=2166
and then today copied to the nmh-workers list.
Basically, using "sortm -textfield subject" where a message
in the folder contains "Subject:N" where "N" is alphanumeric
will cause sortm to dump core (the "korean spam" aspect of the
mail that caused the original bug report is irrelevant).
>How-To-Repeat:
Use nmh. Put a message in a folder that contains "Subject:1234"
and then run
sortm +whatever-folder -textfield subject
and watch for the core dump.
Or, examine the code and be amazed ...
