� � I've found a bug in�ContextPart>>#runUntilErrorOrReturnFrom: that in a certain rare circumstance causes the method to peel back too much of the stack. �This method is used in the debugger (e.g. completeStep: et al) but also in Process termination. �So it is right at the heart of the system. �I'm loath to simply commit it �I'd really appreciate y'all testing with the fix and reporting any changes you see. �It does not affect the trunk test suite (there is a test, WeakSetInspectorTest, which is unreliable, but apart form that no observed effects). �So, brave souls, please try with the attached and see if you come to grief or not.
