           Summary: Mono core dumps when reaching uninitialized object
                    through reflection

sample code of reflection bug in mono

Problem:
When using reflection (FieldInfo arrays) to iterate through object fields, mono
core dumps at runtime when reflection tries to use GetValue on a field with the
object as argument (see attached sample code)

Expected behaviour:
I would expect an ArgumentException, as access on fields of uninitialized
objects should be an exception.

Attached is an example tested with gmcs version 1.2.6.0 and Mono JIT compiler
version 1.2.6, revision 90732
