[mapserver-users] Memoryproblem

Wed Aug 13 07:09:52 PDT 2008

Hello

I have MapServer 5.2.0 and I have built the bin by myself. I use Windows Server 2003 standard edition.

I also have tried to turn off all layers in the file and I have also removed all layes from the mapfile and still there is the same problem.

Here is the file:

Johan,

I wonder if this was a Win 2003 issue, since all of the windows builder are running on Win 2003 at the buildbot and the build process includes testing the getBytes function.

How is your mapfile looking like? Which mapserver version are you testing with.

The output below doesn't actually write the error but the "GetBytes:" is the first part och the exception message. I can guess that the memory already is corrupt. When I do the same with the debugger you can see the watch output below.
