Looks peculiar enough to say: I don't understand half of what is written there. Is the compiler not deterministic anymore?

Unit1.pas.20: begin
0041A868 55               push ebp
0041A869 8BEC             mov ebp,esp
0041A86B 6A00             push $00
0041A86D 6A00             push $00
0041A86F 6A00             push $00
0041A871 53               push ebx
0041A872 8B5D08           mov ebx,[ebp+$08]
0041A875 8B5B0C           mov ebx,[ebx+$0c]

 

ebx is very well initialized

You have probably changed the unit; in my environment, access violation occurs, too.

@Vandrovnik How get you run that "unit" without touching it?
