Hello Thomas,
looks good to me. Nice catch the missing "break".

PS: I think it does not exercise a differ code path, but instead of
derived types, using a character string works as well. The following is
accepted with the unmodified trunk:
character(len=4):: str
print *, str(1)(1:4)
Hello world,
I found an ommission in primary.c which prevented issuing a
more specific error instead of "syntax error" for the case
when a function was declared in an EXTERNAL statement,
and I have now gone for the "Unexpected junk after foo"
variant.
Regression-tested. OK for trunk?
Regards

Well, yes. It is no better than what we currently have for the

OK, so here's a patch which doe

I do not understand this error message, and find it to be confusing.
foo(1)%a looks like an invalid

Anyway, the fix is rather straightforward. We cannot have a reference
on a function. If this slipped through on parsing, let's issue the
error during resolution.

I think I am fine with the check it
