I'll try. The problem occured during exit but only when profiling. This meant 
the problem was triggered in the function called at exit when profiling that 
writes out gmon.out. So I disabled the code that wrote out gmon.out and the 
program didn't crash. I then enabled one line, rebuilt libc, rebuilt the 
trivial program and then ran it. If it didn't crash, I enabled one more line 
and repeated the process until the crash occured again. Turned out the crash 
occured in the write call that writes out histogram data. I ran the program 
in rhide, put a breakpoint on that line, and then traced what happened in 
write().
