Log from first bad commit with warn+all,warn-dpa

I am using SSH tunneling and X forwarding to launch Wine by running
(effectively) `wine start "C:\Program
Files\ChessBase\CBase18\CBase18.exe"`, which normally runs ChessBase 18. 
But now, the command never completes until I manually stop the wine processes.
