Created a new solution from template project iphone c sharp openGL project. The
call to GL.DrawArray ... caused a SIGSGEV fault.

Reproducible: Always

Steps to Reproduce:
Requirements: Install xcode 3.2.6 and ios sdk 4.3. Install Monotouch 3.2.6 and
Monodevelop ver 2.4.2

1. Create new solution iphone C Sharp Open GL Project. 
2. Run project with no changes.

Actual Results:  
The application runs showing rotating colourful square (expected)
It also runs slower (cant confirm this) (unexpected)
Finally a fault below is (unexpected) application output:

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

Terminating in response to SpringBoard's termination.
Error connecting stdout and stderr (127.0.0.1:10001)
Thread 0x0 may have been prematurely finalized


Expected Results:  
Expects app runs showing rotating sq no faults.


I tried reinstalling everything xcode, sdks and monotouch and monodevelop The
problem is there. This appears after the recent updates following the ios 4.3
sdk + Monotouch + Monodevelop releases.

Debuging the application the fault occurs in the call to GL.DrawArray( )
Couldnt debug any further despite having debug source may be not for openTK
