I've been using -march=pentium4 for a year or so with various versions
of gcc without any of these optimization related problems. Can you
produce some backtraces?

This is easy enough to add, but can you produce some backtraces so we
can see what is causing the crashes? 

Usually people are complaining to me about the lack of optimization. ;)
