Using the attached repro I still get a SIGSEGV (see below).
To reproduce:
1. extract the gzipped tar archive.
2. run 'make'.

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