Sounds like an interesting bug :-)
A couple of suggestions:
(1) try using strace and see whether any system calls look funny
(strange arguments, unexpected failures.)
(2) Since you say the ps_app itself gets corrupted, set up a background
process to checksum the app every second or so. Then run ps_app under
the debugger and see if you can narrow down when the corruption occurs.
It's possible you're passing bad arguments to a system call and they
aren't being properly checked.
