Are you sure about this?
I ran with this trace: https://www.cs.utexas.edu/~fussell/courses/cs352.fall98/Homework/cc1.din.Z and Valgrind doesn't think there are any leaks:

When you pass to a.cacheRead(address(addr))
or a.cacheWrite(address(addr))
you're just passing a copy of a new instance, not a pointer (which would be a.cacheRead(new address(addr))
)
The read/write functions use the copy from the stack frame and it is cleaned up when that frame is removed.
When you pass these around from the read/write functions, you're not passing pointers or addresses, so it looks like you're copying out to other functions, too.

Also I don't think Address() is even necessary if we move index/offset/tag parse responsibility to the cache ( #1 )
