Hi, all
The XWin crashes that were cured with snapshot-20050407 reappeared with
cigwin-1.5.15-1. See

---------------------------------------
This is what the alert window of W98 shows when the crash is produced
by shutting down the XWin server.

XWIN caused an invalid page fault in
module KERNEL32.DLL at 0167:bff87ed3.

The XWin.log and cygcheck -s output are attached

As the problem is obviously related to  cygwin1.dll I am sending this
message to both mail lists.
