             Bug #: 50178
           Summary: [4.6 regression] ICE with gfortran -O3, not with
                    gfortran -02
    Classification: Unclassified
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: middle-end
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: toon@moene.org


Created attachment 25089
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25089
Source code of the failing compilation.

Compiling the attached source code with gfortran 4.6.1 using optimization -O3
leads to the following Internal Compiler Error:

$ gfortran -O3 -c suedyn.f90 
suedyn.f90: In function ‘suedyn’:
suedyn.f90:10:0: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.

Compiling with -O2 instead succeeds (hence my suspicion that it is a middle-end
failure).
