The following testcase causes an ICE in the current gfortran.
The code seems ill-formed to me, because the name "n"
was already defined as a constant in the module scope,
but I'm not sure.
This was originally reported by Vivek Rao ([EMAIL PROTECTED]).
module zz
integer, parameter :: n=2 ! causes ICE
contains
subroutine xx(n)
call yy(n)
end subroutine xx
end module zz
