If I remember correctly andreas wrote the tests. I always like them. Stef
The author of the test is Andreas Raab, but I'm not sure who found it (excavating mailing list is hard work)

Still, I do not see how you get the errorSubscriptBound:... In Squeak that would mean that you sent #handleSignal: to a not isHandlerContext ContextPart... I never saw this, but if Eliot says so...

good find :)

ok, it seems i found how to reproduce the situation with following:
[ [ 1/0 ] ensure: [ nil foo ] ] on: Error fork: [ :ex | 1halt ]
you will get halt, and if you close the debugger , it will throw unwind error. (while instead it should throw DNU)
