Issues Running TPSScript on x64 in Lazarus 3.8

I'm using TPSScript, and the code below works correctly on x86.
However, when I compile it in x64, it doesn't run. Does anyone know
why? 
I'm using Lazarus 3.8 64x.

My Script:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
fechar(Sender: TObject; var CloseAction: TCloseAction);begin 
 Showmessage( 'Vou fechar' );end; procedure exec;var F: TForm;begin 
 F :=  TForm.Create(NIL);   try      F.OnClose := @fechar;     
F.ShowModal;   finally      F.Free;   end;end;

I saw https://forum.lazarus.freepascal.org/index.php/topic,71170.msg57

Unfortunately I don't know the answer.

I also don't know if your event method (the code to be called) is
- in pascal script
- in the compiled exe, but to be called by the script
?

In any case, I know some case are not implemented, search the source
for:
(at least I think that is the related part / needs to be double
checked)
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i {$ifdef
fpc}  {$if defined(cpu86)}         // Has MyAllMethodsHandler 
{$else}  // {$if defined(cpupowerpc) or defined(cpuarm) or
defined(cpu64)}    {$define empty_methods_handler}  {$ifend}{$endif} 
I don't know what the planned solution for that is.

IIRC (but rather like a faint memory) there was talk about using RTTI
calling... Not sure, I think that requires fpc 3.3.1 and depending on
OS also some external library (dll/so). But I may be mixing that up.

---
In any case, the version of Pascalscript included in Lazarus is
primarily for supporting editor-macros in the IDE.

It will occasionally be updated, but for your own projects you may
still need to download from the original side if you require up-to-
date fixes.
