[Rd] segfault with layout() after closing X11() device (PR#8970)

[ripley at stats.ox.ac.uk]

I unable to reproduce this on my Solaris 8 64-bit systems (neither 
compiled with gcc nor cc) nor any other 64-bit system.

If possible, can you run R under a suitable debugger (e.g. R -d gdb for 
gcc) and find out what is pointing to address zero.
