Out Of Memory & Invalid Pointer exceptions on CSV export

Iu2019m having problems when exporting more than 1 million rows of data to a CSV format. Iu2019m running the export from C# code (see sample code below). Depending on the template that I use, I get either a System.OutOfMemoryException or a System.Runtime.InteropServices.COMException (Invalid pointer) error. See the full error text below.

This worked fine with Crystal XI but now breaks with Crystal 2008.

Is this a known problem and are there any workarounds?

Sample Code:

ReportDocument rptDoc = new ReportDocument();

rptDoc.Load("C:\somereport.rpt");

ExportOptions opts = new ExportOptions();

opts.ExportDestinationType = ExportDestinationType.DiskFile;

DiskFileDestinationOptions destOpts = ExportOptions.CreateDiskFileDestinationOptions();

destOpts.DiskFileName = "C:\outputfile.csv";

opts.ExportDestinationOptions = destOpts;

opts.ExportFormatType = ExportFormatType.CharacterSeparatedValues;

rptDoc.Export(opts);

Configuration:

Crystal Reports 2008 (Full Version)

C#

.NET 3.5

VS 2008
