another identical case (not attached, with a stack trace)

It looks like mono_get_delegate_invoke callers (about 15 of them) should check
|
|
for NULL (and, worse case scenario, assert). That would leave
|
|
verify_delegate_compatibility (inlined in the previous stack trace) able to
|
|
call ADD_VERIFY_ERROR and fail correctly.
