Me too I get from time to time a VM crash (sometimes after a smalltalkhub hiccups). Stef Le 8/8/16 à 15:26, Mariano Martinez Peck a écrit :

For the record, I do also continue to see this crash in Pharo 5.0 with it's stable VM. But as Esteban said, it's too random that I don't have more info to share :(

damn :( FreeType bug strikes again… :((

to be honest, I’m playing with the idea to completely replace it with a UFFI version. I cannot find why/how this happens… in some conditions handle become invalid and pharo has no idea pointer is not valid any more… then crash. Double free was what I guess but I do not find where that happens (the double free). And I’m also open to believe in some memory handling problem in VM, now :((
