            Bug ID: 68968
           Summary: Internal Compiler error
           Product: gcc
           Version: 5.3.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org

Compile this as indicated in the comments and get a segmentation fault in the
compiler

test.F90 attached gives an internal compiler error (Segmentation fault) when
compiled with

gfortran -Dplet_=\'q\' -o test test.F90

If gfortran is replaced by cpp in the above, it seems to generate what one
would expect.
