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

I think I've found a regression in gfortran with list-directed reading
from character arrays: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60810
unless this is some kind of new standards compliance, but this seems to
have worked forever.
Any project I tried with
./configure CFLAGS="-fsanitize=undefined -fsanitize=address"
fails with:
checking for gcc... gcc
checking whether the C compiler works... no
config.log reveals that libasan.so and libubsan.so are missing from the system.
"yum install lib{a,ub}san.{i686,x86_64}" fixed it. Shouldn't gcc and gcc-c++
packages require these libraries?
