When I downloaded 20040324, I also confirmed the problem with the PLplot
library (the only part of PLplot used by yplot).  Further checking with
valgrind showed a memory management problem in plcont.c was causing the
segfault.  Sure enough, in the cvs log messages for plcont.c as of March 26
(two days after the tarball) we have the following commit message from
Andrew Ross:

"Fix bounds check in plcont. Also (partially) fix problem contouring
flat surface."

So to summarize, Valery, you ran into a problem for the 20040324 tarball
(confirmed by me) and in the Debian unstable packages corresponding to that
tarball that has now been fixed in cvs (confirmed by both of us).  Sorry I
didn't clue in faster. Your report is much appreciated since it highlights
how important that plcont.c fix is.

As a matter of course, that important fix will be included in the next cvs
snapshot tarball and also the corresponding set of Debian packages since
they both currently track cvs HEAD.
