Updated status: We were able to trace it down to some sort of library conflict. If we have certain of our own libraries in LD_LIBRARY_PATH, this happens. My guess is that we've got a library that's conflicting with some system library. If I add /lib:/usr/lib to the front of LD_LIBRARY_PATH, the crash doesn't happen. Note that this is all done as an unprivileged user. So to me this makes it a security issue... all a user has to do is drop a library in their home directory, clear LD_LIBRARY_PATH except for that library location, and he can make the system crash. Still working on isolating it down to a simple case I can pass to you. interesting, what do you mean by conflicting? i'd guess that the other libraries are making different syscalls and thus causing different system dynamics. pretty strange though...it'd be great if you could narrow this down further.
