Comment 1 Miguel de Icaza [MSFT] 2012-01-09 15:41:09 UTC
We need a test case.
Comment 2 Sergey Pachkov 2013-01-31 08:26:36 UTC
we have tried mono-2.10.9 and mono crashed in GC again.

issue described in https://bugzilla.xamarin.com/show_bug.cgi?id=9938
Comment 3 Sergey Pachkov 2013-01-31 08:28:44 UTC
different mono versions (2.6.7, 2.10.6, 2.10.9) crashes in with one application.
