Firstly, thanks very much for trying it out and reporting the problem.

I don't believe IPv6 is the cause of the problem you are seeing, this just 
happens to be the last line of output written.

You could test this by adding '-nolisten inet6' to the command line used to 
start the X server.

If the suggestion above fails, I'd like your help to get a backtrace, if you 
are willing:

1. Download ftp://cygwin.com/pub/cygwinx/XWin.20090628173519.exe.bz2
(this is a build of the 1.6.0.0-1 X server but with debugging symbols unstripped)
2. bunzip2 XWin.20090628173519.exe.bz2 to uncompress it
3. gdb --args ./XWin.20090628173519.exe  -multiwindow -clipboard -logverbose 3
(you may need to install the gdb package)
4  wait for the '(gdb)' prompt, type 'r'
5. wait for the segmentation fault to occur, you should get another '(gdb)' 
prompt, "bt full"
6. post the output
