Comment #1 on issue 137 by dominiqu...@gmail.com: Memory fault-coredump

The stack provided is not very useful unfortunately.
The debugger is not able to show the stack beyond the signal
handler 'deathtrap' somehow.
I would suggest to comment out the set up of this signal handler, and try
to reproduce the bug. The stack trace will then hopefully be more useful.
In other words, try to comment out the line "catch_signals(deathtrap,
SIG_ERR);" in os_unix.c:1332 as follows:
diff -r fcd8be759157 src/os_unix.c

Then provide the stack again.
I don't have IBM AIX so I cannot reproduce this. But I used
IBM AIX a long time ago and I remember one difference with Linux:
malloc(0) returned NULL on AIX whereas malloc(0) returns a
valid address of 0 allocated bytes on Linux. Well, I see that
Vim lalloc() treats 0 size allocation as error so I don't think
that's the issue anyway.
I also see that you're also using Vim-7.3.754. The latest version
is Vim-7.3.1224. It would be best to reproduce it with the latest
version if possible, in case the bug has already been fixed.
You could also try to download the latest Vim with Mercurial:
$ hg clone https://vim.googlecode.com/hg/ vim
