This is the IL code crashes Reflector when switching to C# (or VB.NET)
mode. I've marked the culprit lines. If I ldnull instead of ldtoken,
Reflector doesn't bug out anymore. It happens on all woven methods,
not just this one. It's kind of important that this work, since
developers may need to debug the woven code... Suggestions are much
appreciated.
Thanks.
