The following patch is trivial: Normal procedures with character
argument come with a hidden length argument, which can be used with
-fcheck=bounds to check whether the actual argument is smaller than the
dummy argument.

However, BIND(C) procedures do not have any hidden argument; thus
accessing the non-existing argument leads to an ICE. The fix is trivial:
Don't add the check for BIND(C) procedures.

Build and regtested on x86-64-linux.
OK for the trunk?

Ok.

Thanks for the fix!
