In the testcase below, compiled with:

    gfortran -c test.f90

gfortran suffers an internal compiler error:

internal compiler error: in gfc_gen_symbol_decl, at fortran/trans-decl.c:893

If the commenting on the marked line is removed, then the code compiles fine.

I have tested this case with versions 4.3.2, 4.4.1 and 4.6 (experimental, from
svn trunk last night). It works correctly using ifort, PGI and pathscale
compilers.

---------------------------------------

module test_mod

    implicit none

contains

    subroutine test_fn (cmp)

        interface operator(.myop.)
            pure function cmp (a, b) result(ret)
                integer, intent(in) :: a, b
                logical ret
            end function
        end interface

        integer :: a, b

        !print*, cmp(a, b)   ! If this line is commented out, gfortran has an
                            ! internal compiler error
        print*, a .myop. b

    end subroutine

end module
