Hi,

A trivial code, like this:

procedure TForm1.Button1Click(Sender: TObject);
begin
   Edit1.Text := '';
end;

Will generate a exception without useful stacktrace on Qt4 / Mac

Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: KERN_PROTECTION_FAILURE at address: 0x00000000 0x00009d1c in fpc_widestr_decr_ref ()
(gdb) bt
#0 0x00009d1c in fpc_widestr_decr_ref ()

wierd .... maybe that's related to the problem we solved on Linux by using the try .. except block

did U try to put there try..except and see result ?

yep ... didn't work

Must be yet another widestring problem.

hm...did U try to compile your own libqt4intfs for Mac ? I cannot get Dens libqt4intfs to work on my distro (raises floating point errors), so I have to compile my own libqt4intfs.

yes, I compiled my own Qt and then my own qt4intf

windows version also raises AV , try .. except fixes problem.
