Debug info from gdb:
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
This happens when handling exceptions in our heavily multi-threaded F# application. I do not think it is always deterministic. Have not found a small repro example yet, will post if I do.
Mono JIT compiler version 3.2.8 (tarball Mon Mar 3 12:37:20 UTC 2014)

Could you try mono 3.4.0 ?
Also, before the assertion, the runtime should print out a number to standard output. Does that happen ?
Since we've moved on to Mono 3.4.0, I have not been able to reproduce this. Thanks!
marking as fixed.
