Re: multiwindow + XDMCP + X0.hosts == crash

I suspect SMP has something to do with the bug... Also, when I reproduced the problem from a Cygwin shell, I got a message I had not seen before: 3 [main] XWin 3440 pthread_conf::Signal: Released too many threads - 1 now 1 originally I probably missed this before because I was running XWin.exe from a .bat file. Anyway, the crash still happens. My /tmp/XWin.log file is appended. What can I do next to help fix this?

multiwindow + XDMCP + X0.hosts == crash
This is with Cygwin 1.3.22, XFree86-base 4.2.0-1, and XFree86-xserv 4.2.0-42. The crash occurs both with Windows 2000 and XP. I downloaded Cygwin+XFree86 yesterday, and I am able to crash XWin.exe routinely. To reproduce on a fresh Cygwin+XFree86 installation, do: echo localhost > /etc/X0.hosts XWin -multiwindow -query ...where is a machine running an XDMCP server. Things appear to work at first. But within a few seconds, XWin.exe crashes with an access violation. This does not happen if I remove /etc/X0.hosts. (Are you wondering why I want to do this? I want to run xwinclip, which must run locally, but I also want to use XDMCP to connect to remote machines. When I start XWin with the -query, -indirect, or -broadcast options, it does not permit localhost to connect.) Any suggestions would be appreciated. Also, I would be glad to provide any additional information needed to reproduce and/or debug this problem. Thank you! - Pat
