So you're right, the issue is not unexec related

So you have a few irregular crashes, more or less related to memory allocation.
If this is applicable to your AIX version, can you try some recipes from the
following article:

The previous run uses "temacs" from a new build using those suggested 
"configure" parameters,

These parameters assumes '-O2 -g3' or at least '-g', so your gdb backtrace 
include file names, line numbers and (some) function parameters. But your 
looks like from stripped binary or the binary compiled without debug info.

(gdb) where
#0  0xd0508b20 in pthread_kill () from /usr/lib/libpthread.a(shr_xpg5.o)
#1  0xd0507f8c in _p_raise () from /usr/lib/libpthread.a(shr_xpg5.o)
#2  0x1000c4f8 in terminate_due_to_signal ()
#3  0x1003483c in emacs_abort ()
#4  0x10020a04 in xfree ()

How the emacs_abort() was called here? AFAICS xfree() doesn't call it directly.
