HEAP CORRUPTION (0xc0000374, C:\Windows\System32\ntdll.dll)

Hi,

Good Day!

I am new to Heap corruption so I would like to ask to understand the Full Call stack from dump.

The function is for exporting data to CSV and PDF. Export to CSV was successful, there was no generated PDF so the export to PDF was unsuccessful. Please note that this problem rarely happens, sometime once per 1 month or every other month, meaning.

Here is the Full Call stack stated in the Dump file

{
DataSet ds = ReportUtility.FileToDataSet(dataFormatFile, dataFile, csvCharSet);
return this.ExportPDF(reportFormatFile, dataFormatFile, ds, targetPDFFileName);

throw err;
}

if(!File.Exists(dataFormatFile))
{
FileNotFoundException err = new FileNotFoundException("Unable to load data format file.", dataFormatFile);
throw err;
}

if(dataSet == null) {
Exception err = new Exception("Unable to load data.");
throw err;
}

ReportDocument rd = new ReportDocument();
rd.Load(reportFormatFile);
rd.SetDataSource(dataSet);

DiskFileDestinationOptions crDiskFileDestinationOptions = new DiskFileDestinationOptions();
crDiskFileDestinationOptions.DiskFileName = targetPDFFileName;
rd.ExportOptions.DestinationOptions = crDiskFileDestinationOptions;
rd.ExportOptions.ExportDestinationType = ExportDestinationType.DiskFile;
rd.ExportOptions.ExportFormatType = ExportFormatType.PortableDocFormat;
rd.Export();
// close the report document to release resources.
rd.Close();
rd.Dispose();
