I'm using FWTools and SharpMap (with gdal_sharp) to build an application. And I have a weird error. Loading a raster layer runs great in Debug mode, but in Release it throws an Exception in SharpMap.Layers.GdalRasterLayer in the constructor when calling
_projectionWkt = _gdalDataset.GetProjectionRef();
The full exception is:
{System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

The weird thing is that in Debug everything works fine. The build setup is exact, both .Net 4.0, x86 Platform.
Any ideas?
Thankyou in advance
It seems to be a problem with Windows 8 and it's DEP implementation along with .Net 4.0. I'm using a C++ dll in a wrapper, and the OS does not let it execute. It could be solved by editing the DLL or turning Data Execution Prevention off.
