           Summary: ICE on valid code involving power of small integer
                    kinds
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: domob@gcc.gnu.org


The following reduced code ICEs:

PROGRAM main
  IMPLICIT NONE
  INTEGER(KIND=2) :: j

  j = 1_2 + 1_2**j
END PROGRAM main

I get something like:

[/tmp]# gfortran-dev test.f03 
test.f03: In function 'MAIN__':
test.f03:1:0: error: type mismatch in binary expression
integer(kind=2)

integer(kind=4)

integer(kind=2)

j = D.1476 + 1;

test.f03:1:0: internal compiler error: verify_gimple failed
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

The problem is that for "small" integer kinds (1 and 2) we still call the
library power routine for kind 4 but the result is not converted back to the
smaller integer kinds properly.

This seems to be a regression, with 4.3 and 4.5 the code compiles cleanly for 
me.
