Segfault when a gnuplot graph is closed?

[Atwood, Robert C]

Dear folks: 
I have gotten a segmentation fault repeatedly when using a plot (gnuplot) of
the information in a dynamically-allocated array (pointer), when the plot is
closed, or closing a non-active plot. The display 

(gdb) graph display (*bp->sb[0]->c_fs)@100 

updates without any problem, but if I have a gnuplot graph open, run to the
same breakpoint again (same scope, same source line) and use the file|close
command from the plot window. it segfaults. It also segfaults if the
debugger is stopped at a breakpoint outside the original scope, even though
the variable exists in the new scope, and even thought he plot is not active
when closed. 


I hope this is some sort of easily fixed issue of configuration?
