             Bug #: 56260
           Summary: GCC hangs/crashes on potentially invalid source
    Classification: Unclassified
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: novulae@hotmail.com


This came from http://www.glenmccl.com/cpp11.htm, and was part of the free
sample of tests.

Originally this hung for me. Now it just causes a ICE/segfault.

This was with GCC 4.7.2, on Ubuntu 12 x86_64.

$ gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/data00/opt/pkg/gcc-4.7.2/bin/../libexec/gcc/x86_64-unknown-linux-gnu/4.7.2/lto-wrapper
Target: x86_64-unknown-linux-gnu
Configured with: ../gcc-4.7.2/configure --prefix=/opt/pkg/gcc-4.7.2
--program-suffix=-4.7.2 --enable-languages=c,c++ --disable-multilib
Thread model: posix
gcc version 4.7.2 (GCC)
