--- Comment #14 from Gert van den Berg wine-bugs@mohag.net 2010-12-21 10:56:52 CST --- Created an attachment (id=32576) --> (http://bugs.winehq.org/attachment.cgi?id=32576) WINEDEBUG=+win log - no crash
Like with warn+all, debugs made the crash stop. The debug info, including seemingly the trace from line before the assert might be of use. (around line 27860 in the log)
