Yes, there have been core dumps in NtCurrentTeb as
delivered with Wine for the last three releases.

I had put in a work-around for this problem for the
latest Wine "port" (980104) commited to FreeBSD: 
Just return NULL unconditionally (see patch-au).

When I tried to upgrade the port to Wine-980118, I
found that I could not get the Emulator to start.
It dumped core immediately, even though I had put
in the NtCurrentTeb() work-around.

I have already fetched Wine-980201, but did not
yet find the time to build that version. Maybe I
get around to try it next weekend.
