[squeak-dev] Morphic yellow cross of deathBob Arning arning315 at comcast.netTue Sep 17 00:55:20 UTC 2013
Well, I can sort-of make it happen
- do you have the full SqueakDebug.log?
- did you copy the portion you sent from the file or did you do it
another way? (like the mail bug report menu item)???
- you might think about upping the numbers in
ContextPart>>errorReportOn: so we can see the full stack next time
[snip]
strm position > (startPos+40000) ifTrue: [strm nextPutAll:
'...etc...'. "make 40000 much larger"
^ self]. "exit early"
cnt > 60 ifTrue: [strm nextPutAll: '-- and more not shown --'.
^ self]. "make 60 much larger"
[snip]
Cheers,
Bob
