[mapserver-users] Memoryproblem

Johan,
Could you try this out with a debug build? You can change the OPTFLAGS
section in nmake.opt by commenting out the # Debug with MSVCRT
section.
You should also add /debug:full to the csc command line in
/mapscript/csharp/makefile.vc
Finally you should enable the just in time debug option in the Visual
Studio IDE.
I hope this will help to locate the function that causes the problem
in the mapserver core.
Best regards,
Tamas
