Dim j, r, v
Set j = CreateObject("JDLLServer")
Set j = Nothing ' Comment this to see Done before crash
WScript.Echo "Done"
VB Scripts has deterministic memory model, so
j = Nothing calls Release immediately.
If you comment the above line, Release is called
when script goes out of scope, so you see
message Done before the crash.
DoR has nothing to do with it.

No the crash is inside Release on the J object.
DoR is fine. (Inless DoR or something else damages the stack,
because there is stack warning in the Stack view in VS.)
The crash inside Release was traced there with the debugger
in disassembly view.
On the other hand, the v result is fine, it prints out both from
J and from VB script. In J it is shown how VariantClear works
fine on it.
I will do more testing with and without DoR to see if it damages
the stack.

I am not able to look at this right now, but will eventually. Could you
perhaps confirm that 'some things' or even 'most things' work and that
the problem is just with DoR? Most of the COM code hasn't changed in a
long time, but there were a few changes in the area of DoR that were
related to utf8. It will be easier to track down if I know to look
directly at the DoR utf8 stuff.
Also, please clarify why you say 'crashes on Release'. Your example
seems to indicate simply that the v result from DoR is damagaed.
