BUG: C0000005 Fatal Error Using GETPEM() in Loop with Debugger

ID: Q221745

The information in this article applies to:

Microsoft Visual FoxPro for Windows, version 6.0

SYMPTOMS

Placing the GetPem() function in a loop while tracing the code more than once in the Debugger causes the following error in Visual FoxPro 6.0:

Fatal error: Exception code: C0000005

Note that the error message also contains information regarding the line number of the program running when the error occurred.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.

The Visual Studio 6.0 Service Pack 3 readme file erroneously lists this bug as having been fixed. Service Pack 3 did not fix this bug.

MORE INFORMATION

Steps to Reproduce Behavior

Create a program called Ztest.prg that contains the following code:


DO doit
CLEAR ALL
DO doit

PROC doit
	SET EXACT ON
	oForm = CREATEOBJECT( "Form" )
	oForm.ADDOBJECT("lbl1", "label")
	FOR EACH loObject IN oForm.OBJECTS
		m = AMEMBERS( laMembers, loObject )
		lcClass = loObject.CLASS
		FOR j = 1 TO m
		IF ( ! pemstatus( loObject, laMembers[j], 1 ) )
		luClassValue = getpem( lcClass, laMembers[j] )
			ENDIF
		ENDFOR
	ENDFOR
ENDPROC

Close and save the program.

Open the Debugger and open the Ztest.prg file.

In the Debugger, click the Resume toolbar button.

You can also get this error by simply running the code in the example above. In Visual FoxPro 6.0, if you run the program using either the DO command or by pressing the Run button (!) on the standard toolbar with the program open, the C0000005 error appears. In Visual FoxPro 6.0 Service Pack 3, only the DO command causes the error.
