           Summary: XScreenSaverSetAttributes broken on 64 bit architectures
           Product: xorg
           Version: CVS_head
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Server/general
        AssignedTo: xorg-bugzilla-noise at freedesktop.org
        ReportedBy: matthieu.herrb at laas.fr


Lauching beforelight on OpenBSD/amd64 or OpenBSD/amd64 lead to a BadColor error:
X Error of failed request:  BadColor (invalid Colormap parameter)
  Major opcode of failed request:  136 (MIT-SCREEN-SAVER)
  Minor opcode of failed request:  3 ()
  Resource id in failed request:  0x2b000001
  Serial number of failed request:  94
  Current serial number in output stream:  95

Afaict, this is caused by a mismatch in the length of the fields used to decode
the request in Xext/saver.c. The attached patch is a proposed fix, but I'm not 
sure if it's correct. It would be great if someone more familiar then me with
the request decoding code checked that before I commit it.
