APPLIES TO


 * Microsoft Windows CE 5.0

SYMPTOMS
Consider the following scenario:
 * Two applications that use the DirectDraw API are running on a Microsoft Windows CE 5.0-based device.
 * One application creates and then releases a primary surface.
 * The second application creates a palette object.
 * Later, the second application exits unexpectedly.

In this scenario, an exception occurs when the first application calls the CreateSurface function. When the exception occurs, the user receives the following message:

37007 PID:cfe928d6 TID:2fd9731a 0x8fcae6f4: Exception 040 Thread=8fcae6f4 Proc=cfe928d6 'gwes.exe' 37007 PID:cfe928d6 TID:2fd9731a 0x8fcae6f4: AKY=00000051 PC=cccccccc(???+0xcccccccc) RA=02aaf10a(ddcore.dll+0x0005f10a) TEA=cccccccc



CAUSE
When the second application exits, Windows CE releases the Ddhel.dll file. When Windows CE releases the file, the global reference count (gblrefcnt) value in the DD_Release error flag is decremented incorrectly because the first application still requires the Ddhel.dll file. Therefore, when the first application calls the CreateSurface function, and the gblrefcnt value is incorrect, the exception occurs.
