Hi,
I am having some more issues in domain unloading. Paolo fixed one
crashbug in the generics cache and at least it isn't crashing every
time we unload a domain.
http://bugzilla.ximian.com/show_bug.cgi?id=77596
The problem is that now i am getting crashbugs much less frequently
and it happens in places that just don't make a lot of sense to me
and it happens very rarely. After unload/loading a domain 40-50
times. I get crashes which look like this:
So now i really have no idea how to debug this. Any ideas on what to
do here? On how to debug this situation. Any hints on what might be
going wrong?
I am stumped.
See crashlogs below.
In this one, it seemed that the return value of the signature was
null and then got derefenced.
