Steps to Reproduce Behavior
---------------------------

1. Create a PRG and type in the code below:

  PUBLIC oform1
  oform1 = CREATEOBJECT('form1')
  oform1.SHOW()

  DEFINE CLASS form1 AS FORM
  	ADD OBJECT pf1 AS PAGEFRAME WITH ;
  		PAGECOUNT = 0
  	PROCEDURE pf1.INIT()
  		THIS.ADDOBJECT('pg1', 'pg')
  	ENDPROC
  ENDDEFINE

  DEFINE CLASS pg AS PAGE
  	PROCEDURE ACTIVATE()
  		NODE
  	ENDPROC
  ENDDEFINE

2. Save and run the PRG.

Immediately after the PRG runs, the Fatal Error occurs and Visual FoxPro
terminates.
