I can try, but since much software out there produces aliasing warning, 
I always build with

-O2 -g -Wall -fno-strict-aliasing

Not sure, whether the original bug also occured when using 
"-fno-strict-aliasing". I also vaguely remember the original bug 
happened only with gcc 4.5 or 4.6, not with 4.1.2.
