Steps to Reproduce Behavior

1. Cut and paste the program below into a .PRG:




x1 = CREATEOBJECT( "cBigArray" )
x1.aBig[1,1] = 1
x1.aBig[1000,1] = 1
x1.aBig[10000,1] = 1
x1.aBig[30000,1] = 1

DEFINE CLASS cBigArray AS Custom
   DIMENSION aBig[33000,2]
ENDDEFINE 

2. Save and run the .PRG.
   
   NOTE: Visual FoxPro causes a C0000005 Fatal Error and terminates.
   
   After the fix in Visual Studio Service Pack 3, Visual FoxPro shows this error message when the maximum allowed value is greater then 32500 on a two- dimensional array:

   Too Many Variables
