Comment 1 Oleg Demchenko 2016-09-12 16:57:31 UTC
I can reproduce this crash when running unit tests with UnitTests pad:
https://gist.github.com/olegoid/8261891806c7dd14e7bb4daa95193c85

With Beta(XamarinStudio-6.1.0.5436) and stable(Version 6.0.2 (build 73)) builds.
Comment 2 Oleg Demchenko 2016-09-15 16:47:32 UTC
Moving this bug to SR1 release since we have a workaround for that. Instead of running unit tests from XS users can do it with nunit-console.
Comment 3 xamarin-release-manager 2016-09-16 11:58:26 UTC
Fixed in version 6.2.0.498 (master)
