You could start with this one:
imadev:~$ bash-4.2.28 -c 'a() { echo "$1"; a $(($1+1)); }; a 1' 2>&1 | tail
Pid 4466 received a SIGSEGV for stack growth failure.
Possible causes: insufficient memory or swap space,
or stack size exceeded maxssiz.

imadev:~$ ls -l core
-rw------- 1 wooledg pgmr 19908052 Oct 3 08:38 core
imadev:~$ file core
core: core file from 'bash-4.2.28' - received SIGSEGV
That was executed on HP-UX 10.20. I agree that bash should try not
to dump core in this case, if it's reasonable to prevent it. There
was some confusion in the earlier part of this thread due to the
introduction of valgrind into the picture, and incomplete quoting of
previous messages.
