I was able to re-create the bug with this testcase. ICE happens with 4.7 compiler and not with 4.6. gcc -O5 -c ./job.i ./tools/src/make-3.82/job.c: In function ‘construct_command_argv_internal.isra.1’: ./tools/src/make-3.82/job.c:3073:1: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate. See file:///usr/share/doc/gcc-4.7/README.Bugs for instructions. The bug is not reproducible, so it is likely a hardware or OS problem. ** Attachment added: pre-Processed testcase https://bugs.launchpad.net/ubuntu/+source/gcc-4.7/+bug/1116769/+attachment/3529096/+files/job.i -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1116769 Title: Unreproducible ICEs on Cortex A15 To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1116769/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
