When I attach a message from mailbox (shift+a in send window, select
folder, tag messages and "q" ... oops) mutt (often) crashes:
segmentation fault (core dumped) mutt
$ gdb mutt core
#0 0x40275c34 in __libc_realloc (oldmem=0x40316688, bytes=161)
---Type <return> to continue, or q <return> to quit---
3289 malloc.c: No such file or directory.
% rpm -q mutt glibc slang
With RH7.0 it never happend but with RH7.1b and Rawhide it happens.
AFAIK, this was a compiler issue that's fixed with the current compiler.
