wine and jack => segfault? / wine and OSS not working

[Chris Morgan]

There is something funny that wine is doing that causes jack to have
issues under wine.  I haven't been able to debug any of the recent
issues since a year ago but maybe someone with more knowledge of
threading can try winejack out and see if they can at least figure out
what area the issue may be in.
