             Bug #: 54134
           Summary: ICE overriding derived type bound function with
                    allocatable character as result
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: koen.poppe@cs.kuleuven.be

Code that reproduces the ICE with the correct output from two other compilers.

Consider the derived type A with no-pass type bound function which has an
allocatable character string as result. Now extend this type A with a type B
which overrides that function. The combination of this overriding and the fact
that the result is allocatable results in an ICE. Removing the inheritance from
A and/or changing the result type to a fixed length character string does not
trigger the ICE as shown in the attached example.
