             Bug #: 50227
           Summary: ICE on valid with allocatable class component
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: abenson@caltech.edu


Created attachment 25128
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25128
Contains the files which constitute the test cases.

The attached code causes an ICE with gfortran 4.7 r178129. Note that if I 
combine the code in the two files into a single file (as in the attached 
combined.F90), and compile that it works without any problem.

$ gfortran -v
