Yep. I suspect it may be a glibc/gcc issue.
I have gcc-3.2-7, glibc-2.2.93, libstdc++-3.2-7

This one did not work for some reason -- whatever I set gnuplot_binary
on the command line it is still would just use what I had in .octaverc.
It did work when I set this variables in .octaverc.

Here is an output:

set data style lines
set mouse
set mouse labels
set nologscale
set nopolar
pl '/tmp/oct-lhS0vw' t "line 1",\
   '/tmp/oct-ufULMS' t "line 2",\

   '/tmp/oct-EEvlLq' t "line 6",\
   '/tmp/oct-3wwFeP' t "line 7",\
   '/tmp/oct-M7mHFd' t "line 8"


(And there are only 8 oct-* file in /tmp)

File oct-3wwFeP looks kind of funny:

which is in fact contains data from other files. In particular, the second
column is just the file oct-lhS0vw (line 1). So line 7 just overrides
plot line 1. (That explains dissapearing plot.)

Hope it is of some help.
