This is enough to open a bug, can you do that? -Steve -----Original Message----- From: mapserver-users-boun...@lists.osgeo.org [mailto:mapserver-users-boun...@lists.osgeo.org] On Behalf Of Oliver Christen Sent: Tuesday, November 15, 2011 7:15 AM To: mapserver-users@lists.osgeo.org Subject: [mapserver-users] crash mapserver with some specific jpeg output and truetype symbol over raster
hi all Im experimenting some weird behavior with some jpeg output on a Mapserver 6.0.0 I have two layers: a raster layer and a watermark using a truetype symbol over it. When requesting the jpeg output, at the very specific FORMATOPTION QUALITY=88, Mapserver crash with a "Floating point exception". The image is still generated (???), but the error make it impossible to server the image with fastcgi, as the Mapserver error trigger an error 500 in apache. I DONT have any problem if: 1) I request a png image 2) I change the FORMATOPTION QUALITY=88 to 87 or 89 I have prepared a minimal testcase which allow to reproduce the problem: http://publicshare.camptocamp.com/mapserver/testcase.zip which can be triggered with: shp2img -m testcase.map -l "ch.swisstopo.pixelkarte-farbe-pk200.noscale ch.swisstopo.watermark" -i jpeg -s 256 256 -e 624800.0 132400.0 625440.0 133040.0 > test.jpg or: /usr/lib/cgi-bin/mapserv -nh "QUERY_STRING=map=testcase.map&mode=map&layers=ch.swisstopo.pixelkarte-farbe-pk200.noscale+ch.swisstopo.watermark&mapext=624800.0+132400.0+625440.0+133040.0&mapsize=256+256" > test2.jpeg I just had a look using gdb (but I dont have enough knowledge to get any info from this sadely): gdb /usr/lib/cgi-bin/mapserv GNU gdb (GDB) 7.0.1-debian Copyright (C) 2009 Free Software Foundation, Inc.

Could someone tell me if it is "enough" to open a bug?
