--- Comment #1 from anlauf at gcc dot gnu.org ---
The code crashing gfortran may actually be valid.
Consider:
module m
implicit none
type t
end type
contains
subroutine s
real :: t
common /com/ t
end
end
This is accepted by other compilers, including Intel and NAG.
With -fdump-fortran-original we see that memory gets clobbered somewhere
if the derived-type name is the same as the common variable.
