You have a Schrödinger bug, i.e. one that changes when you observe it.
Since you are running Linux, I'd suggest you try out valgrind,
http://valgrind.kde.org/. It's a debugger that will usually catch
most kinds of memory related bugs.

Browse the list of groups and find those that look appropriate to you.
Then fetch the FAQ for those groups, and see if it looks right. It
might even answer your question.
