Also I found another funny issue. Try debugIt following expression:

1 ifTrue: [2].

You will be wondering that debugger will not able to open.

To quickly get to the point to observe the cause, you can insert... Halt if: [interruptedProcess suspendedContext receiver == nil]. into DebugSession>>stepInto: just after the send of #step. Then when you step into Context>>stepToSendOrReturn step once over "context := self step" and the second time step in until you get to Context>>jump:if: which substitutes the following context Context sender: self "=Undefined>>DoIt" receiver: rcvr "=1" method: newMethod "=Object>>#mustBeBoolean" arguments: args "=#()" such that in RubSmalltalkEditor>>debug:receiver:in: the condition block debugSession stepIntoUntil: [:currentContext | currentContext method == aCompiledMethod ] always fails, so in DebugSession>>stepIntoUntil: the #whileFalse: never exits. A possible fix (if a bit hacky) is... debugSession stepIntoUntil: [:currentContext | (currentContext method == aCompiledMethod) or: [currentContext method selector==#mustBeBoolean] ]. cheers -ben
