Pharo image corruption and fatal VM error with Roassal

by Blondeau Vincent

Hi, Yesterday, I was using GraphET (a part of Roassal) to do some charts and, today, when I wanted to reopen the image. And I got that : [cid:image001.png@01CFACAA.E0CB2060] It is *very* unpleasant... To reproduce the bug: 1 - You can do either: | builder | builder := GET2Line data: (0 to: 100) . builder y: [ :x | x*x ]. builder open. Or WorldMenu -> Roassal examples -> choose an item -> click on a graph . A TRMorph should be opened. 2 - don't close the graph and save the pharo image. 3 - Close the pharo image 4 - Reopen it I am under W7 x64 with the latest moose image and the VM available on the pharo.org website (http://files.pharo.org/platform/Pharo3.0-win.zip) from the 10 july. You will find the crash dump attached. Thankfully, I managed to open the image with a latest VM (http://www.mirandabanda.org/files/Cog/VM/VM.r3056/cogwin-14.29.3056.zip) Thanks a lot Eliot ! :) And I got this: [cid:image002.png@01CFACAD.350D7DB0] Thanks in advance Cheers, Vincent BLONDEAU ________________________________ Ce message et les pi?ces jointes sont confidentiels et r?serv?s ? l'usage exclusif de ses destinataires.
