Yes, verify_types misses a call to itself for every element that is an arra=
y.
I think we should not reject all mismatching types, because there is a call=
 to
gfc_type_convert_binary further down that is able to handle conversions on
numeric types.  Basically all numeric types, even if mismatching, should wo=
rk.
That's the second solution.=
