OK.
The stack trace is:

*** buffer overflow detected ***: gnuplot_x11 terminated
======= Backtrace: =========
/lib/libc.so.6(__chk_fail+0x41)[0x586c45]
gnuplot_x11[0x804aaa2]          Find_Plot_In_Linked_List_By_Number
gnuplot_x11[0x80576b6]          mainloop (gplt_x11.c line 1326, I think)
gnuplot_x11[0x8059319]          main


I can't see how Find_Plot_In_Linked_List_By_Number() would ever
cause a buffer overflow, but all eyes are invited to stare at the
code.  I wonder could it possibly be a malloc() problem?
