[fpc-pascal] PascalScript / FPC: parameters problems (need internals gurus I think)

The actual procedure that is called. It does some asm processing and
then calls the MyAllMethodsHandler2 that works with parameters. Maybe
this is there that there is a problem? (This is all in the
uPSRuntime.pas file)

procedure MyAllMethodsHandler;
//  On entry:
//     EAX = Self pointer
//     EDX, ECX = param1 and param2
//     STACK = param3... paramcount
  push 0
  push ecx
  push edx
  mov edx, esp
  add edx, 16 // was 12
  pop ecx
  call MyAllMethodsHandler2
  pop ecx
  mov edx, [esp]
  add esp, eax
  mov [esp], edx
  mov eax, ecx
