[Bug fortran/21415] New: internal compiler error in gfortran -fdefault-integer-8

["jiri dot pittner at jh-inst dot cas dot cz" <gcc-bugzilla at gcc dot gnu dot org>]

The following file.f causes the following error:
gfortran -fdefault-integer-8 -c fi.f
fi.f: In function 'bug':
fi.f:1: internal compiler error: in gfc_conv_string_tmp, at fortran/trans-expr.c:736
----
Without -fdefault-integer-8 works just fine.
fi.f:
      SUBROUTINE bug
      CHARACTER*6 S
      CALL something(S//'X')
      RETURN
      END
The error happens both on an opteron machine with
GNU Fortran 95 (GCC 4.0.0 20050406 (Red Hat 4.0.0-0.41.fc3))
and on a pentium machine where I compiled gcc4 myself
GNU Fortran 95 (GCC 4.0.0)
