Synopsis: mismatch in size of empty class
State-Changed-From-To: open->closed
State-Changed-By: aoliva
State-Changed-When: Fri Aug 31 05:20:29 2001
State-Changed-Why:
Not a bug. Padding is required to maintain alignment. GCC 3.0 optimizes empty base classes away entirely, so you'll see the size of the class is 4, not 8 or 5.
