Which is entirely correct and has been like that since the beginning of
ages :-)
By the time you're looking at the stack of "thisContext sender", the 4
values are not there anymore because they have been moved into the stack
of thisContext. Look at Interpreter>>internalActivateNewMethod, near the
bottom of that method it says "self internalPop: argCount2 + 1". That's
where your stackPtr changes from 4 to 0.
If you would look at the sending context just prior to the send
bytecode, you'd see a stackPtr of 4.
