again, this is an attempt against the "Font crashing VMâ bug⦠please I need all reports possible⦠even if you think is the same as before (even if IS the same as before). thanks! Esteban
TX esteban I will try my super crashing power to see if I can. I just need time to code :) Le 16/3/16 13:36, Esteban Lorenzano a écrit :

Ok, I started following Ben's breadcrumbs. I'm on debian jessie also, 64bits. First, I could reproduce the issue (only if I maximize the image). And I started looking at the debugger/stack trace. The first thing I noticed is that with the debugger open in newFaceFromExternalMemory: aFreeTypeExternalMemory index: anInteger If I retry to evaluate self primNewFaceFromExternalMemory: aFreeTypeExternalMemory size: memSize index: anInteger. This always fails. I checked the Freetype plugin an the freetype library doc and my only guess is that the first argument (aFreeTypeExternalMemory) is wrong, or a remanent from another session. BUT! I made another discovery. If we actually walk to the top of the stack, we will see - the failure happens at startup, while starting up WorldMorph (what would explain why people observe this issue when saving the image) And, the redrawing happens because I maximized the window, what forces the morphs to redraw, explaining somehow why the bug appears when we maximize the window (?). - and then if we evaluate SessionManager default startupList we will see that WorldMorph is being started up before freetype. This means that the WorldMorph is being redrawn before freetype objects are cleaned, which may cause having wrong freetype handles/values. Of course, I'm half-way understanding all what's happenning :) These are all conjectures. But nevertheless, if somebody wants to try, I made a changeset (attached) that should be filed in and two lines that reset the session manager SessionManager default: SessionManager initializedSessionManager. SessionManager default installNewSession. Guille On Wed, Mar 16, 2016 at 7:09 PM, Ben Coman <btc@openinworld.com> wrote:
