[PATCH fortran/95342] - [9/10/11 Regression] ICE in gfc_match_subroutine, at fortran/decl.c:7913

[Harald Anlauf]

Dear all,

two almost obvious, trivial issues issues with NULL pointer dereferences.
Steve found the locations, but his solution changes the error messages
as compared to 7/8.  I've chosen the conservative way which keeps the
documented intent of the source code.

Regtested on x86_64-pc-linux-gnu.

OK for master?  Backport to affected 10- and 9-branches?
(8.4.1 was/is fine).

Thanks,
Harald
