MORE INFORMATION
The following DWORD registry key causes failfast on out of memory conditions when it is set to a non-zero value:

If you set the value of the key to 1, an event message is logged in the application event log. If you set the value of the key to 2, you experience a break in the debugger.

If you set the value of the key to 4, an event message is logged that includes the size of the allocation that failed and the number of bytes in use: Failed to allocate x bytes with y bytes in use. Process will be Terminated.

If you configure the registry key, one of these two events will occur:
 * The application calls the DebugBreak function, and then you experience a breakpoint exception.
 * The application creates a log event message. The log event message describes what Private Bytes are in use, and then it describes the size of the VirtualAlloc function that the application did not allocate.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
