--- Comment #7 from Dan Kegel dank@kegel.com 2012-06-21 12:12:27 CDT --- Doesn't sound like a real memory problem somehow.
Wonder what was different on that first run where you had the crash.
Can reproduce the bug? If not, not much we can do.
http://bugs.winehq.org/show_bug.cgi?id=21973 mentions a similar problem, supposedly fixed.
