             Bug #: 52310
           Summary: Internal Compiler Error when building lesstif with
                    -Wp,-D_FORTIFY_SOURCE=2
    Classification: Unclassified
           Product: gcc
           Version: 4.6.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: pterjan@gmail.com

gcc: internal compiler error: Segmentation fault (program cc1)

I attached the preprocessed source, it crashes here (x86_64) when using gcc -g
-c XmStringE.c with gcc-4.6.2

This preprocessed source builds fine using gcc-4.5.1 (even if it gives a lot of
warning about casting pointers to int).

Reduce source code leading to the crash

Here is the minimal code I managed to trigger the crash
