It seems that the (new for Cygwin 1.7) getifaddr() function can return
interfaces with IFF_BROADCAST & IFF_UP set, but no broadcast address, which
the X server assumes never happens
I'd guess this means you have a network interface with a slightly unusual
state (connected but no address configured perhaps?)
I've uploaded a new build of the X server with a small patch (attached)
applied which should avoid this crash, perhaps you could try
ftp://cygwin.com/pub/cygwinx/XWin.20090629103603.exe.bz2 and see if that works
any better...
