Hi Yuriy Pay attention (It happens to me) that you control which VM is launched.

I’ve encountered a situation where pharo crashes, and when I run it from command line I get: "Segmentation fault: 11". Also before that some trace appears starting with highlighted: "MessageNotUnderstood: ToolDockingBarMorph>>popUpEvent:in:”. I’ve also updated my Pharo launcher and now stack trace disappeared (probably because now I have to specify some flag), but the problem remains. Should I report this to pharo issue tracker, or this is a VM problem and it should be handled in a different way? Can you give us more information: - image - VM version - a reproducible case
