Hi Robert, 

thanks for the hints. Unfortunately running in Pharo 5 is not feasible. PhaROS does not do any low-level calls as far as I am aware (I did not implement it, I’m just using it).

I will try to run it in gdb as soon as I can find a reliable way to reproduce the crash.

The VM crashes after a random amount of time (< 25 minutes), with no clear sequence of steps on how to reproduce the crash. I am using Pharo 4 (Pharo 40622 as installed by PhaROS) + Roassal which required an install of libcairo2:i386 . VM version details below.
