I also have to scroll up to see the last frame (Pharo 5.0).

In fact my test was broken an in addition the debugger does not show the
top frame and it took me a while to see that I
should always scroll to be the stack.
And I was always only seeing this mustBeABoolean.

Hi,
I am not quite sure where the issue is because I cannot seem to
reproduce the problem.
I try this Playground script:
Object subclass: #ABC
        instanceVariableNames: ''
        classVariableNames: ''
        package: 'ABC'.
ABC compile: 'doesNotUnderstand: aMessage
        "support sending message to access properties"
| selector |
        selector := aMessage selector.
        self halt: aMessage selector.
        ^ selector isUnary
                ifTrue: [ (self hasPropertyAt: selector)
                                ifTrue: [ self propertyAt: aMessage
selector asSymbol ]
                                ifFalse: [ super doesNotUnderstand:
aMessage ] ]
                ifFalse: [ selector numArgs = 1
                                ifTrue: [ self propertyAt: aMessage
selector allButLast asSymbol put: aMessage argument ]
                                ifFalse: [ super doesNotUnderstand:
aMessage ] ]'.
ABC new bla.
And I get a debugger. What am I missing?
Cheers,
Doru

Hi
In the past it was possible to step throw such code and now we cannot
anymore
because of a smart trick. I should say that I hate when we break the
reachibility and understandibility of the system.
So why I cannot get a debugger opens after the halt: ?
How do I get that ?
Now I will put traces: super cool!
