Dear Alan Here is my report, First I tryied the way which you recommended. I rebuilt plplot from tarball plplot-5.3.0.cvs.20040324.tar.gz. I got the same segmentation error . Then I downloaded the cvs tree and again rebuilt the library, and found that everything's tip-top (ok!). So something was wrong with version 2004032. best rgds, Valery Right now, The bug (or something like this) is Alan W.
