Regarding the test case in comment #1, the difference between the c2-args of
'sub' and 'fp' is that the former has IFSRC_UNKNOWN, while the latter has
IFSRC_DECL.
The latter symbol is created by 'gfc_copy_formal_args', and therefore an
alternative (and probably preferable) patch would be:

... which is not a real problem, I guess (since the error message is fake
anyway).
