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.
=================================================================

oops, above is a second test case - with another icall used from System.dll
here's the one for the above stack trace:

Do not define DISABLE_PROCESS_HANDLING since this will remove some icalls that the class librairies requires - e.g. regression from #709278
