mono crash

I have multi threaded application(test runner). In each thread(number of threads is the number of parallel running tests) in cycle new application domain is being created, some code is being run in AppDomain and then AppDomain is being unloaded.
If start 1 thread then error not occurs, if start more threads then at some moment application fails with the following:

Debug info from gdb:


=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.

Mono crash report is attached.

Reproduces not always.

Pitko,

I'd like to apologize on the long delay in responding to this bug. It was misfiled and thus overlooked in our system.

Unfortunately without a reproduction case, it is difficult to determine if this has been fixed in newer versions of Xamarin.Mac / Mono. I'm going to close this issue (due to its age), but if after testing with newer versions you still run into it, please either reopen or file a new bug with steps to reproduce and we'll get back to you much more quickly this time.
