Hi! FYI, gcc in rawhide has been upgraded to 4.9.0 prerelease, please visit http://gcc.gnu.org/gcc-4.9/porting_to.html if your package no longer builds. To investigate runtime rather than compile time issues, please consider using temporarily -fsanitize=undefined and/or -fsanitize=address to look for undefined behavior in the packages you own.
