Just an update, this will be fixed in the upcoming 5.4 release.

I changed my Geos to version 3.0.3 and the error changed from "Segmentation
fault" to "Bus error".
I also looked at the ticket Assefa indicated below and am wondering if that was
related to the buffer or to the same problem I am having? The script I am
having problems does nothing more than create a new shape object from a wkt and
then re-output the wkt from the shape object. The object seems to be created
fine, because I can get the number of lines with $drawnShp->numlines. I can
also create a new shape object with the other shape object constructer as
follows and the output works.
<Xphp
dl('php_mapscript.so');
$drawnShp = ms_newShapeObj(MS_SHAPE_POLYGON);
$line = ms_newLineObj();
$line->addXY(1207657,478875);
$line->addXY(1208230,478275);
$line->addXY(1207452,477811);
$line->addXY(1207043,478520);
$line->addXY(1207657,478875);
$drawnShp->add($line);
error_log($drawnShp->numlines);
error_log($drawnShp->towkt());
?>
Is this specifically a problem with Geos 3.1 and the function
ms_shapeObjFromWkt()? Which version of Mapserver will have the patch in ticket
2929?
Thanks,
Paul

Not helping here but I have tested your script on windows with Mapserver
5.2.2 and 5.4 and the script runs ok. The geos version used in this
case is geos 2.2.3. Do you know what version of geos you are using?
There was a recent fix done toward geos support in MapServer and the
problem from what I remember was occurring with geos 3.1 (Is that
correct Tom ?)
