Fun with VB6. Crashes in OLE gunk...

[Dan Kegel]

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:
