I had the same problem. The solution was to change the Mapserver, before
compiling, to use the "OGR" instead of "GEOS" in the routine generation
of WKT

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.
<?php
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 ?)
