[mapserver-dev] problems with AGG in Mapserver 5.2

[Karsten Hoffmann]

Dear developers,

I have problems with AGG in MapServer 5.2.0 (ms4w 2.3.0).

I want to create a layer with TYPE CHART and a legend. But mapserver crashes
and I get an internal server error too.

The error message is: „Die Anweisung in „0x100db369“ verweist auf Speicher
in „0x00000000f“. Der Vorgang „read“ konnte nicht auf dem Speicher
durchgeführt werden.“

It happens only if I create a legend. In &mode=map all works fine but in
&mode=legend mapserver crashes.
In Mapserver 5.0 (ms4w 2.2.6) I had no problems with the same mapfile and
data. And with using GD (instead of AGG) in Mapserver 5.2 it works too. 
I also have the same problem with a Layer with the Symbol Hatch. So it
doesn’t only happen with the CHART Layer.

In the Apache error.log is written:
[Thu Oct 16 13:12:21 2008] [error] [client 127.0.0.1] Premature end of
script headers: mapserv.exe, referer:
http://localhost/cgi-bin/mapserv.exe?map=C:/ms4w/Apache/htdocs/fossgis08/wes
er2.map

I have the same problems on two different machines with the same
configurations:
Windows XP SP3, ms4w 2.3.0 with UMN 5.2.0 and Apache 2.2.9

Could this be a bug? Perhaps it has something to do with the ms4w package? I
used the Dependency Walker on the mapserv.exe and got the following:

Warning: At least one delay-load dependency module was not found.
Warning: At least one module has an unresolved import due to a missing
export function in a delay-load dependent module

The module DWMAPI.DLL cannot be opened. The system doesn’t find it.
