R devel - Jun 2006 - segfault with layout() after closing X11() device (PR#8970)

Full_Name: Don Maszle
Version: 2.3.0
OS: Solaris 9 - 64 bit compile
Submission from: (NULL) (206.86.87.3)


After closing an X11() window by either clicking on the close button
or by calling dev.off(), R 2.3.0 segfaults as shown below.  Calling layout()
before any X11() device is opened just opens a new device and applies the
layout.

 *** caught segfault ***
address 0, cause 'memory not mapped'

Traceback:
 1: X11()
 2: layout(matrix(1:2, 1, 2))

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.
