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. The C0000005 error appears.

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.
