--- Comment #1 from G. Steinmetz <gscfq@t-online.de> ---

This related valid case also ICEs, but down to r6 :


$ cat z2.f90
module m
   interface
      module subroutine f(n, z)
         integer, intent(in) :: n
         real :: z(n)
      end
   end interface
contains
   module procedure f
      z = 1
   end procedure
end

Thanks for nailing down the commit for addon comment 1.

But when started the regression/issue from comment 0 ?
gfortran 9.3 does not have the ICE.
