Do you have any more details available somewhere I can see them? Maybe in Fedora's bugzilla or on the devel@ list?
The issue is only affecting 64-bit wine. A bug is opened but doesn't contain much additional information.

Although -fno-strict-aliasing is unlikely to make any difference because strict aliasing is only enabled at -O2 and above. You can also try -fsanitize=undefined to detect undefined behaviour at runtime.
As seen in my other e-mail, strict aliasing is disabled by wine. I attempted to build with the sanitize option, but gcc loops indefinitely when compiling "tools/makedep.c". I let it sit for several hours before breaking out. Wine normally takes about 5 minutes to compile on my machine. I can add the sanitize option to gcc 4.9 and it compiles makedep.c in a second.
Thanks, Michael
