The Lpq.exe tool crashes in Windows Vista SP2 or in Windows Server 2008 SP2

Symptoms

On a computer that is running Windows Vista or Windows Server 2008, when you use the Lpq.exe tool, the tool crashes.
For example, consider the following scenario in a network environment:
  • You enable the LPD Print Service and LPR Port Monitor features on a Windows Server 2008-based print server.
  • You share a printer as a network printer by using the LPR port.
  • You pause the printing on the printer, and then you print many documents to the printer.
  • You run the following command on a client computer that is running Windows Vista Service Pack 2 (SP2) or Windows Server 2008 Service Pack 2 (SP2):
    Lpq.exe -S <ServerName> -P <SharedPrinterName>
In this scenario, the Lpq.exe tool crashes. Additionally, you receive a 1073740940 application error.

Cause

This issue is caused by a heap corruption in the LPRPutMsg function.
