[Mapserver-users] Segmentation Fault -- reference image -- PHP

[Ed Martin]

i am using the map file and map stuff from the cvs mapserver (did not 
compile from cvs, i used the stable version 4.0.1) and when i try to 
get the reference image using a very simple script i get the jpeg 
header an then a segmentation fault when run in the command line and a 
blank page when in a browser, turning off the jpeg header still gives 
me a blank page

here is the php file i am using

<?
require_once('../inc/conf.inc.php');//get config
//load mapscript
dl("php_mapscript.so");
header("Content-type: image/jpeg");
// start map
$map=ms_newMapObj("tests/test.map");
$img=$map->drawReferenceMap();
$img->saveImage('');
?>

and here is the reference part of the map file

#refence map
   REFERENCE
     IMAGE ./reference.jpeg
     EXTENT -0.5 50.977222 0.5 51.977222
     SIZE 120 120
     STATUS ON
     COLOR 255 255 0
     OUTLINECOLOR 255 100 0
     STATUS ON
     MARKER "line"
     MARKERSIZE 5
     MINBOXSIZE 50
     MINBOXSIZE 100
   END

i have output set to jpeg and changing the reference image to jpg or 
png doesn't help and i tried gif and that gave an error saying that it 
couldn't load it (probably because gifs aren't supported by gd, but 
this page ( 
http://mapserver.gis.umn.edu/doc40/mapfile-reference.html#referencemap 
) says it has to be a gif)

could it be the way i made the reference image, i just took the main 
image, cropped out the boarder, shrunk it to 120x120 and saved it in 
various formats

i see nothing in my apache logs, but i know it is logging to them 
because a parse error will show up, i have error reporting set to the 
highest (E_ALL), i'm using mapserver 4.0.1, php 4.3.4 as CGI, apache 
2.0.48, slackware linux 9.0

so does anyone have any clue as to what is causing this, my map file, 
do i have to put more stuff in the php file, is it the way i made the 
image, or is it a bug
