Hmm, this example is OK in Maxima 5.11.0cvs + GCL 2.6.7 + Linux,
both with plot_fomat = gnuplot_pipes (default on Linux) and
plot_format = gnuplot (writes a file instead of a pipe).

Aside from recompiling wgnuplot to get the debugging symbols,
the only thing I can think of is to inspect the maxout.gnuplot file which
is created by plot3d -- it is written to the folder named by maxima_tempdir.

Hope this helps
