I think everyone should exercise a little caution with switching to 4.9.0
right away. There is a code generation bug that results in flac generating
bad data, and who knows what else. There is a fix on the gcc mainline
branch, but not on 4.9.x yet. You could certainly cherry-pick it and have
it for the build until4.9.1 appears.

Thanks for pointing this out. The fix appears to be at
http://gcc.gnu.org/viewcvs/gcc/trunk/gcc/tree-ssa-threadedge.c?r1=209716&r2=209715&pathrev=209716
If we don't get a new version soon, we can try using that as a patch.
