I haven't solved this yet but a small follow up:=20
- I'm using the latest stable release : 4.0.1, not 4.1 as stated below.=20
- The crash happens when using any non Lat/Long projection. Any Lat/Long
projection number I chose returns a map via the WMS client, and a blank
image via the web browser.=20

Subject: [Mapserver-users] WMS Projection Error Causing Mapserver to
Crash (Win32)

Hi,=20
I've been trying to set up a WMS server for some UK Ordnance Survey
maps.=20
The map uses some MapInfo layers that I inherited from elsewhere, all
using the British National Grid projection.=20
I have set up a WMS server on a machine which responds correctly to the
GetCapabilities request.=20
It also responds with a map if I use a Url such as=20
http://myIPAddress/cgi-bin/MapServ40.exe?map=3DC:\inetpub\gis\wwwroot\OSM=
a
pServer\OS.map&SERVICE=3DWMS&VERSION=3D1.1.0&LAYERS=3D&FORMAT=3Dimage%2Fp=

.ogc.se_inimage
Note this request does NOT contain an SRS parameter. The map returned is
correct and in the correct BNG projection.=20
As soon as I add the SRS=3DEPSG:27700 parameter to the URL the cgi
application crashes and the browser returns=20
"The specified CGI application misbehaved by not returning a complete
set of HTTP headers. The headers it did return are:" - none
If I use a WMS client layer to the server in another working map file
the following occurrs:=20
1. Using SRS EPSG:27700 in the WMS SRS metadata crashes the cgi
application.=20
2. Using SRS EPSG:4326 in the WMS SRS metadata returns a map with the
requested WMS layers - but in the wrong projection.
Am I doing something wrong here?=20
or=20
Is this a bug in the WMS code and is there a work around?=20
Many thanks=20
Craig.=20
p.s I'm using MapServer 4.1 from the windows binaries. Win2K, IIS, Dual
hyperthreaded pentium 4=20
