second test case

Another test case. This is using System.Windows.dll from 2.1 (Moonlight, not
the 4.0 class libs)

MONO_PATH=/opt/mono/lib/moonlight/plugin/ gdb --args mono --security=core-clr
--compile-all System.Windows.unknown.22130.dll 

** ERROR:(loader.c:663):find_method: assertion failed:
(from_class->interface_offsets_count == in_class->interface_offsets_count)

Program received signal SIGABRT, Aborted.
