gcc version 4.7.0 20120106 (Red Hat 4.7.0-0.5)

Comment 2 Dan Horák 2012-01-12 09:48:58 UTC
and last note - it's on s390 (31/32 bit), s390x (64 bit) is OK

Comment 3 Jakub Jelinek 2012-01-24 07:46:27 UTC
Should be fixed already in gcc-4.7.0-0.8.fc17.  Note, not sure what's going on in the s390 buildroots, but gcc-4.7.0-0.9.fc17 doesn't build there, it dies already very early in configure scripts, would need to see config.log what exactly is going on, but probably something is wrong with the compiler or its dependencies that are in the buildroots right now.

Jakub, I'm looking what's wrong right (the compiler segfaults) now and will let you know the result.
