[Help-smalltalk] JIT and ContextPart/Exception issue

[Holger Hans Peter Freyther]

Hi,

I am currently toying with Phexample (an extension of SUnit) and implement
the "visitor" for the CompiledCode and wanted to use the JIT for that.

Object subclass: PhexampleInstructionMatcher [
    bytecodeIndex: anIndex with: aParam [
        Transcript nextPutAll: 'BC '; nextPutAll: anIndex printString; nl.
        anIndex printNl.
    ]

    lineNo: aLine with: aParam [
        Transcript nextPutAll: 'Line '; nextPutAll: aLine printString; nl.
    ]
]

st> (CompiledCode >> #examineOn:) dispatchTo: PhexampleInstructionMatcher new 
with: nil

Result on JIT:
Object: PhexampleInstructionMatcher new "<0x40445ec0>" error: did not 
understand #pushSelf:
MessageNotUnderstood(Exception)>>signal (ExcHandling.st:254)
PhexampleInstructionMatcher(Object)>>doesNotUnderstand: #pushSelf:

Paolo any idea where we can start to look for the issue?
