I can confirm it as an fpc bug.

No, I'm sorry to say that IMO you did not. I looked at your
code.

<br>
It simply works by accident in Delphi, because you are calling a
method of the same object as the caller.

Yes, the code is wrong. But the reason is that myMethod is
assigned in FormCreate. The later "@myMethod := pMethod;"
assignment overwrites only half of the myMethod:TProc variable and
so correct Self stays in the second half of myMethod.
<br>
<br>
Remove FormCreate and you get an AV.
<br>
<br>
Furthermore, "Format('0x%P',[@Myself])" doesn't make sense - it
should be "Format('0x%P',[Pointer(Myself)])".<br>
<br>
No bug at all - just wrong code.
