Is it possible to run undumped (i.e. temacs) on AIX? If there is an issue with
unexec, it shouldn't affect undumped executable.

Latest backtrace (with SIGSEGV in malloc) is probably caused by heap corruption.
Are there some built-in debugging facilities in AIX malloc implementation
(something similar to glibc mcheck, for example)?
