Description

Class constructors for generic classes do not run if all code is in a .dpr file.

Moving code to a separate .pas unit is sufficient to workaround the problem.

Steps to Reproduce:

The class constructor in the following program is not executed.

program ClassConstructorBug;

{$APPTYPE CONSOLE}

type
  TTestClass<T> = class
  private
    class constructor Create;
  end;

class constructor TTestClass<T>.Create;
begin
  Writeln('class created');
end;

begin
  TTestClass<Integer>.Create;
end.
