I've noticed that XEmacs never reports when a process started with M-!
coredumps. For instance, try:
M-! perl -e 'kill SEGV, $$'
(Shell command failed with no output)
OTOH, if I append `&' to the command to make it run in the background,
I get:
--- working directory: /home/hniksic/
% perl -e 'kill SEGV, $$'
Segmentation fault (core dumped) 13:57:35
Is this a bug or a feature?
