[Bug fortran/68237] ICE on invalid with submodules

--- Comment #6 from Martin Reinecke <mar...@mpa-garching.mpg.de> ---
Ah, my bad ... I still had an old m1.smod lying on disk from earlier tests!

This slightly changed test case should demonstrate the problem:

module m1

interface
module subroutine bar
end subroutine
end interface
end module m1

submodule (m1) m2

contains

module procedure foo
end procedure

end submodule
