State-Changed-Why:
Sorry, but this is not really a useful report. Please provide
some self contained code and show that it is miscompiled by gcc.
Noone is going to debug a third party application in search for
a gcc Bug just to find out that that application made an invalid
assumption that is no longer true with optimizations turned on.
This is just a wild guess but you may try to compile with
-O3 -fno-strict-aliasing and see if that helps.
