[OpenSmalltalk/opensmalltalk-vm] VM crashes (#252)

 

I have copied the below issue from hpi-swa/smalltalkCI#366.

Hi!

Time to time, the Pharo VM crashes, without any apparent reasons.
For example, in https://travis-ci.org/ObjectProfile/Roassal2/jobs/365943067

VM: 201708271955 https://github.com/OpenSmalltalk/opensmalltalk-vm.git $ Date: Sun Aug 27 21:55:26 2017 +0200 $
Plugins: 201708271955 https://github.com/OpenSmalltalk/opensmalltalk-vm.git $
C stack backtrace & registers:

And a bit below:

It seems to happens randomly

This is a really old VM now, several crashes cases have been fixed since.
I suggest upgrading to a recent opensmalltalk pharo vm and recheck.
Meanwhile I close the issue, no more work will happen here.
