A valid method can never be stored in a pointer, since the former is

That the assignment is valid is Delphi compatible: only the procedure
address is copied.
I can confirm it as an fpc bug.
No, I'm sorry to say that IMO you did not. I looked at your code.
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.
That is what I wanted to indicate :)
Michael.
