Raster Calculator Exception in ArcEngine 10.1

Hi,

We just upgraded from ArcEngine 10 to 10.1 and now the raster calculator does not seem to work anymore.

Whenever I execute the geoprocesing tool, we get a LoaderLock was detected error and we are unable to continue.

If I turn off the Loader Lock exception in Visual Studio, it get's a bit further and the application throws a  C++ Runtime Error R6034 (Application has made an attempt to load the C run time library incorrectly).

If I check the geoprocessing message logs I see a ERROR 000539: Runtime error (AttributeError: 'geoprocessing sys.stdout object' object has no attribute 'write')

When I try to run the same thing in ArcMap's Raster Calculator it works fine.

Any idea what going on? Thanks.

I'm using the following code to execute the raster calculator:

         
String expression = @"'C:\Temp\RasterCalc\dem_pre' * 10";
String outputPath = @"C:\Temp\FloodPlain24";
Geoprocessor processor = new Geoprocessor();

RasterCalculator RasterCalc = new RasterCalculator(expression, outputPath);
FileInfo fileInfo = new FileInfo(outputPath);
try
{
     if (!fileInfo.Directory.Exists) fileInfo.Directory.Create();
     processor.OverwriteOutput = true;
     processor.Execute(RasterCalc, null);
}
catch (Exception ex)
{
     Debug.Assert(false, ex.ToString());
     Debug.Write(GetMessages(processor));
}



The full geoprocessing log is as follows:

Executing: RasterCalculator "'C:\Temp\RasterCalc\dem_pre' * 10" C:\Temp\FloodPlain24
