The runtime causes SIGSEGV when call to a generic method on a field
happens, where the type of the field is an interface.

It should report NullReferenceException.

---- repro ----
using System;

interface ITest
{
	void Foo<T> ();
	void Bar ();
}

class Test : ITest
{
	public void Foo<T> () {}

	public void Bar () {}

	//Test test; // this is OK
	ITest test;

	public static void Main ()
	{
		//new Test ().test.Bar (); // this is OK
		new Test ().test.Foo<int> ();
	}
}


Actual Results:

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

Stacktrace:

in (wrapper managed-to-native)
System.Object:__icall_wrapper_compile_generic_met
hod (object,intptr,intptr) <0x4>
in (wrapper managed-to-native)
System.Object:__icall_wrapper_compile_generic_met
hod (object,intptr,intptr) <0x8d>
in Test:Main () <0x2d>
in (wrapper runtime-invoke) System.Object:runtime_invoke_void
(object,intptr,int
ptr,intptr) <0x6df149e7>

Expected Results:

NullReferenceException in managed area should happen.

How often does this happen? 

consistently.

Additional Information:

This is a runtime problem (as the same code normally result in NRE in
another runtime, and the same binary from another compiler result in the
same on mono).

Fixed in SVN and 1.1.13.
