I have had no Emacs crashes since updating to this Cygwin version two 
days ago (with the same amount of use per day), so this bug seems to 
have been the cause.  Let's see if the other users experiencing the 
bogus assertions stop getting them after this fix makes it into the 
stable release.

(I am still occasionally having Emacs freeze in such a way that it is 
unaffected by a DebugBreak (see 
<https://cygwin.com/ml/cygwin/2006-06/msg00321.html>), but less often 
than the bogus asserts, and likely unrelated.)
