Possible error message improvement?

[Tilo Schwarz]

Hi,

today gfortran fooled my with this error message:


[...]
    call process(f, m)
    1
Error: Type mismatch in argument 'm' at (1); passed CLASS(measurement) to
CLASS(measurement)


It took me a while to figure out what's going on here:

I had two (different) types defined in two different module files with the
same name.

The compiler was right, I wanted to move a derived type but actually
copied it and then modified it.

If something like this happens in the same source, I get


[...]
Error: Derived type definition of 't' at (1) has already been defined
types.f95:7.3:


What do you think about adding a hint like

"You might have defined two different types with the same name"

if and only if the types have the same gfc_typename()? (I would do a
patch.)

(or any other, better line, suggestions welcome)


Or do errors always have to be one line?

Another possibility would be to mention the different modules the types
came from.


Regards,
