GCC: CVS update on Oct 01, 2004 (the same error was for the last 5-7 days, I
just did not investigate in detail).

PC, Linux Redhat 9

Build:
./configure --program-suffix=3 --prefix=/home/dmitrym/tmp/gcc-install
--enable-languages=f95; make

Compilation command line:
gfortran3 -c -o owwepr2.o owwepr2.F

Compiler output:
owwepr2.F:7: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.

The following program owwepr2.F crashes gfortran:

-- snip ---

        module Output
        contains
!
        subroutine plot(Na, J)
          IMPLICIT NONE
          integer :: Na, J(Na)
          return
        end subroutine plot
!
        end module Output
!
        subroutine test(Na)
        USE Output
        IMPLICIT NONE
        integer :: Na
        return
        end

-- snip ---

The code was stripped down to this example. Note the name of variable (Na) the
same in the module and in the subroutine below. Renaming Na to Nb (or whatever
else) in any of the two places allows the seamless compile.
