Hi Denis, �(Hi Michaels, this may be related yo your issue)...
Denis, this is nothing to do with blocks having homes. �It's somewhere in the simulation of RemoteString>>text (used in CompiledMethod>>getSourceFromFile), specifically when UTF8TestDecoders egt involved. �Try the following and you'll see the -261 doesNotUnderstand: which is the symptom of the broken simulation. �Don't know exactly where simulation breaks down (but I suspect primitive invocation). �Anyway this may get you started digging deeper.
| m |
m := ClassWithBlockDecompilation >> #methodWithDecompilation.
ContextPart trace: [ �m getSourceFromFile ] "fails"
| m |
m := ClassWithBlockDecompilation >> #methodWithDecompilation.
m getSourceFromFile "succeeds"
To dig deeper you may want to open up ContextPart class>>trace:on: in a workspace and put in some break-points, e.g. the following halts at the first doesNotUnderstand:. �Work your way back from there to find out where the -261 is coming form (I'm using Squeak 4.1, YMMV).
| aStream m aBlock prev |
(aStream := Transcript) clear.
m := ClassWithBlockDecompilation >> #methodWithDecompilation.
aBlock := [m getSourceFromFile].
prev := aBlock.
