15d6b59e8 by Guy Harris (guy@xxxxxxxxxxxx):

    Check first, then allocate.
    
    While we're at it, the MS-WSP spec says that the array size is unsigned,
    and sizeof is always unsigned, so do unsigned arithmetic when doing the
    multiplication, so we don't have to worry about overflowing the maximum
    int size.
