             Bug #: 53218
           Summary: cmake segfaults on sparcv9
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: tcallawa@redhat.com


Attempting to run cmake causes segfaults in libstdc++ on Linux sparcv9 (32bit).
Here is the gdb backtrace from a core dump:

Also seeing a very similar segfault with source-highlight (same environment,
Linux/sparcv9/32bit userspace):

The segfault is in the system libstdc++ library though: was it compiled with
the problematic compiler?  If no, I suppose this works fine with the system
compiler, so can you find out what the problematic and the system compiler do
differently?

No, the system libstdc++ was compiled with gcc-4.6. How would I find out what
they do differently? (Compiler debugging is rather far from my area of
expertise.)

Do you know the affected programs well enough so as to pinpoint where things go
awry in the executable when it is compiled with the new compiler?  That would
be a good start.
