[Mono-list] random reflection crashes

[Scott Fluto]

We randomly get the flowing system crash runing our unit test under mono and Im not sure if anyhow has run across it. IT doesnt happen all the time but something like once in 10 times, something like that. This is the error we get:


** ERROR **: file reflection.c: line 9694 (mono_reflection_lookup_dynamic_token): assertion failed: (obj)
aborting...
