[Cuis-dev] Another puzzle

[Andres Valloud]

Hello, continuing with the puzzling behavior, here's one from a book 
signature I got back in the year 1999 or so.

a := Array new: 2.
a at: 1 put: #perform:withArguments:.
a at: 2 put: a.
a perform: (a at: 1) withArguments: (a at: 2)

Currently this expression crashes the VM.  Eem... the person that signed 
that in my book is well aware of this example :p.

Even if this doesn't crash, you should still be able to break out of it 
by invoking the debugger.  An infinite loop that you can't interrupt is 
unacceptable behavior too.

Andres.
