[Vm-dev] CogSpur crash on OS X when resizing with Moom

[Bernhard Pieber]

Dear VM developers,

I would like to help debug this. I built my own VM (macOS Sierra 10.12.1, Xcode 8.1 (8B62)). However, even when I use the debug VM (CocoaDebug.app) I don’t get more information on the command line than in the crash.dmp.

I am a newbie when it comes to VM building and debugging. How can I help in the best way? Is there a way to debug this using Xcode?

Bernhard

I had made some changes earlier this summer to handle resizing (manually). Obviously this crash gets triggered by Moom which doesn't follow the manual resize use pattern.

I tried to reproduce it by resizing it manually without Moom. I *think* it happened occasionally when resizing manually, but I could not reproduce it today.
