[Pharo-dev] Unwind error during termination

Ok I have the error too.

Strangely enough, the error is triggered because the third
BlockClosure>>#on:do: context has 2 temporaries instead of 3.

Igor / Esteban do you have a clue ? Why a context would have less
temporaries than expected ? Problem from context creation out of the stack ?

I will try to find some time to look at this problem. Though it is not an
easy one it will take some time to be fixed.
