I finally broke down and bought a copy of VB6 Pro. To install it, I had to pick "win98" mode in winecfg, and ignore a few errors.
While playing around with it, running a test app, I got Wine to crash on a COM problem of some sort. In several ways. Here's one:

Here is the bad error.

A NULL ptr check might help, if (!name) return E_POINTER; or so...
