Did you try running it in gdb and get a clue about what blows?

Is there a particular gcc bug you traced it down to? Because it does
not follow that all changes to program behaviour with different
optimization options are necessarily gcc bugs; it can show up
broken-ness in code that happens to not show symptoms according to how
it is compiled.
