One way to get this right is to use the stack model of evaluation, and
then write a handler that extends the stack on overflow transparently.
I did this for the Alsys Ada compiler and it works fine. Of course this
is very different from the gcc model :-(

(this is just to respond to the claim that no compilers get this right!)
