             Bug #: 53581
           Summary: Segmentation fault when enabling -std=c++0x on
                    template code
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: rggjan@gmail.com


Created attachment 27560
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27560
The code that crashes gcc

When compiling the attached code like this:

g++ foo.cpp

then everything works fine. As soon as I enable c++0x:

g++ -std=c++0x foo.cpp

I get this error:
...
foo.cpp:36:7: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
...

-------------------------------------------------------

The full output of /usr/bin/g++ -v -std=c++0x foo.cpp

Using built-in specs.
