Dear all,

we currently may ICE when array bounds of a dummy argument have
a non-integer type, and the procedure with the bad declaration is
referenced.  The same applies to bad character length of dummies.
We could simply punt in such a situation, as the causing error
seems to be reliably diagnosed, see testcase.

Regtested on x86_64-pc-linux-gnu.  OK for mainline?

This is a really safe fix and potentially backportable to other
open branches.  Would that be fine?

Thanks,
Harald
