The patch http://hg.blaise.ru/public/fpc/rev/544a934d262e (attached)
fixes the following:
-------8<-------
{$Mode Delphi}
type G<T> = class
var X: T;
// EXPECTED: gets compiled
// ACTUAL: 'Error: Generics without specialization cannot be used
as a type for a variable'
class var F: function(const X: T) : G<T> of object;
function Foo(const X: T): G<T>;
end;
function G<T>.Foo(const X: T): G<T>;
begin
result := G<T>.Create;
result.X := X
end;
begin
G<Integer>.F := G<Integer>.Create.Foo;
writeln( G<Integer>.F(42).X = 42 );
end.
-------8<-------
Applied in r47795.

Sven
