I get an ICE when "implicit none" is present in this code:

[olchansk@dork user]$ more test_common.f90
module test_common
  implicit none
  integer foo
  common /luns/ foo
end module test_common
[olchansk@dork user]$
/triumfcs/trshare/olchansk/gcc-tree-ssa/install-20030806/bin/gfortran -c
test_common.f90
test_common.f90:0: internal compiler error: in gfc_typenode_for_spec, at
