Version-Release number of selected component (if applicable):
gcc-4.8.0-1.fc19.s390

The error message looks almost the same as http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55687
Comment 1 Dan Horák 2013-04-02 12:20:22 UTC 
I noticed now -O3 was used, so retried with -O2, it also fails with the same error, and succeeds with -O1
Comment 2 Dan Horák 2013-04-02 12:28:50 UTC 
The same problem exists on both s390 and s390x arches.
Comment 3 Jakub Jelinek 2013-04-02 18:19:19 UTC 
Tracking upstream.
