[fpc-devel] Nasty generics-bug, already known?

[Joost van der Sluis]

Hi all, Sven,

I have a very nasty bug related to generics.

Suppose that I have a unit with a generic-class in it. Nothing more. 
This unit is in a package.

Now I also have a unit which is part of an application. Within this unit 
I specialize the generic class of the first unit.

Now, when I change the first unit. The changed code never makes it into 
my application.

(This has probably to do with the interface of the first unit, which 
does not change)

But also when I remove the original first unit, and recompile the 
package, but do not touch the ppu of the application, the changed code 
is not used. (This because the unit that belongs to the application 
already contains the specialized code from the first unit. It does not 
detect a change in the first unit, so nothings happens.)

The question is: is this a known bug?

If not, I can create an example and a more extensive explanation.

Regards,

Joost.
