[fpc-pascal] Forward Generic Type Declaration Bug

[African Wild Dog]

Hello,

Please confirm if this is a bug.

When I try to compile the unit below I get the error:

"generics_bug.pas(14,43) Fatal: Internal error 2012101001"

It seems the compiler has bug when handling forward generics declaration.

Tested on: Debian Jessie amd64 - fpc 3.0.2

=== CODE ===

*unit* generics_bug;

{$mode delphi}

*interface*


*type*

  IGenericInterface<T> = *interface*; // Forward

  TGenericClass<T> = *class*
  *private*
    FGenericInterface: IGenericInterface<T>;
  *end*;

  IGenericInterface<T> = *interface*
  *end*;


*implementation*

*end*.

===


Regards
