To solve other contouring problems that have been found recently, there has
been a replacement of our contouring algorithm since version 5.3.0, and it
seems to have fixed the problem you have reported.  To be specific, for the
latest PLplot (from cvs) your fortran code produced two identical looking
plots with all contours plotted.

Could you please try the latest cvs snapshot version of PLplot from
http://plplot.sourceforge.net/cvs-tarball/ to see whether that fixes
the problem for you?
