I have a puzzling bug. I've narrowed the scenario down to this code: Cranky»initA a := ((StringMorph contents: '####') color: Color white) position: (0@0). m addMorph: a Cranky»initialize f := Form fromFileNamed: 'hot_air_balloon_mysticmorning.jpg'. m := ImageMorph new. m form: f. self initA. m openInWindowLabeled: 'Cranky'. delay := (Delay forSeconds: 5). [ [ true ] whileTrue: [ a contents: 0 asString. delay wait ] fork I can run this application for hours and hours with no problem. However, if I run it for a while and then close the application and then save/exit the image, the next time I start the image, there is some likelihood it will crash dump. The probability is something like 5-10%. Interestingly, if I remove the statement... a contents: 0 asString. from the infinite loop, I've not been able to replicate the crash. Is there something wrong with the way I'm updating the contents of the StringMorph? -- View this message in context: http://forum.world.st/Morphic-or-forking-bug-tp4948727.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
