--- Comment #7 from manuel.reimer at gmx dot de ---
I've tried to find out when the bug first occured.

This one (oldes 4.9 snapshot, I can get) already has the problem:
ftp://gcc.gnu.org/pub/gcc/snapshots/4.9-20140302/

And this one (newest 4.8 snapshot) doesn't have the problem:
ftp://gcc.gnu.org/pub/gcc/snapshots/4.8-20150129/

Is there any easy way to get snapshots between these two?
