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.

Comment 1 Zoltan Varga 2012-03-02 15:35:31 UTC
Unless this is reproducible, we can't do much with it.
Comment 2 Andres G. Aragoneses 2012-03-02 18:51:43 UTC
Unfortunately it was completely random. I ran it 3 or 4 more times later, and no issue.
Comment 3 Rodrigo Kumpera 2013-09-08 19:08:27 UTC
Please reopen if you find a way to reproduce it.
