Re: SIGSEGV in xorg-1.8.2.0 during -resize operation

[Eliot Moss <moss at cs dot umass dot edu>]

Dear John -- Using the .bz2 you posted to this thread on Sept 7th
or so, I consistently get SIGSEGV on my Windows-7 box whenever
I Sleep or Hibernate the system.  I include the .log file for your
consideration, and the stderr output.  Earlier versions seemed
to do ok.  Is there a simple procedure for winding back?
I am on the latest cygwin.

Regards -- Eliot Moss
