[Mono-dev] crash with nunit

Hi,
I've finally updated to 3.2.8 (recompiled from debian experimental) and
am now triggering the attached segfault approximately every second run.
For further analysis I could run this under master; try to upgrade
nunit; try to get more debugging symbols into the package; try to reduce
the amount of code running to trigger the problem.
The project is open source, so if that would be easier I can provide
public repro steps too.
Please advise,
Thanks David
