Yes, as conformance/variance is restricted by NDR to 32-bit
quantities. The IDL compiler should warn/error without the cast as it
would be silently truncating the value used for computing the memory
allocated for storing the array.

The DCE/RPC specification would be a good start, but there is probably
some MSDN documentation on the limitations of size_is expressions in
IDL.
