Thanks for the reply Jakub.  I see you are "owner" of the Fedora GCC 4.4 
feature.  I appreciate you taking the time.

I have code that suffered from the following GCC bug reports...

1. A problem with floating point calculations, that caused repeatable
crashing one of my apps:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38045
I can work around it by adding this compiler option: -fno-if-conversion 
or by randomly changing other lines of code.
2. A problem with "code reordering" that messed up glibc which affected 
threading code found in wxWidgets wxThread class:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29415
I worked around it by using joinable threads instead of detached threads.

Are the fixes found in 4.3.3 in Fedora's 4.3.2 on Fedora 10?

So I guess I should *not* file a bug report when the ICE is not repeatable?

Thanks again for taking the time to reply,
Pete
