So after many builds, and eventually selectively applying some patches to fix segfaults and build failures, I tracked the problem down to commit 7d957bd8cbcbf56f7916d375e65042d767f544b5 in git (commit 6336 in svn). I wish there weren't so many checkins that failed to build or segfaulted at start. Oh well. Too many targets to test I guess. Now I have been using qemu for a while by doing: 'ssh -X fastserver' and running qemu there. With the new display code this has made qemu very slow and hardly useable. Now if I use vnc to connect to qemu, the performance is great. I suppose I could use that, but I am still wondering why the new display code made the X11 over ssh so awful. Any ideas? Oh and vnc doesn't work with xvnc4client, giving an error about rect too big: CConn: connected to host rceng02 port 5901 CConnection: Server supports RFB protocol version 3.8 CConnection: Using RFB protocol version 3.8 TXImage: Using default colormap and visual, TrueColor, depth 24.
