[squeak-dev] How to crash CogVM or InterpreterVM while debugging BlockCannotReturn

Hi, all.

Try this (on a Windows machine?):

v := [^ true].
v value.

A debugger appears with BlockCannotReturn. Try proceed. The VM will crash.
My image is 4.6, but it also happens 4.5 with a #2776 CogVM. ...and also in
Squeak 3.9 with an interpreter VM. However in 3.9, I can hit proceed at
least once--the second click crashes the VM. 

Why's that?
