Both -O1 and -Os can reorder instructions, and might fool the debugger 
completely.

You should try to produce a small test case that shows the same 
behavior, and show its assembly.

The thing is, what you've shown so far isn't really a problem. If your 
program is in fact misbehaving, what you've shown might not be the cause 
at all.

I hope this helps,
