Hey fellas, 

The testcase attached (bar.cs) consistently generates a SIGSEGV on my
fedora core 5 box running mono and 1.1.14 . The code attached
is basically part of a util class that I use to dynamic set fields in an
object. If you guys think this is a new issue let me know and I'll file
a bug entry for it.

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.

System.Reflection.MonoField:GetValueInternal (object) <0x4>
