    Can anyone tell me if the copy_planes bug
    is strictly a server phenomena or if it also relates to Xlib &/or
    intrinsics.

I'd say the server, but I can't really tell what your bug is.

    The fix that I think is pertinant was given in fix-1 as:
	"CopyPlane sometimes mis-fetches source"

As far as I know this didn't cause a server crash, it only caused bogus
pixels to appear on the screen.

    When I use our client with the R4 server, I get a complete server
    crash (sometimes) when doing a XCopyPlane from a pixmap to pixmap.

As usual, we can't diagnose such problems without information.  Please
supply a test program or some way of reliably reproducing the problem.
Please extract a stack trace from the server core file.  Please tell us
what machine, display, OS, and compiler you are using.  Please supply
any other information you think is relevant.
