[mapserver-users] MS4W Crash: Faulting app: mapserv.exe, module: libmap.dll

[Michael Shishcu]

Hi,

I had the similar issue long time ago with v5.2 that was caused by some
features being actually not simple polygons but lines/complex polygons with
arcs.
I am not sure if this can be the issue you've got, anyway, if everything
else (memory, libs, etc.) seems to be ok, make sure the data is "well".

regards, michael
