--- Comment #12 from Ken Thomases ken@codeweavers.com --- Your most recent attachments do not include the backtrace. Please add that, since there have been recent improvements to backtrace generation in Wine. (Although, you'd need an unstripped build, or build from source, to get the best backtrace quality.)
In attachment 52071, the process was gone by the time winedbg tried to grab the backtrace, but hopefully it will be able to get it this time.
