Should this and the above be ->chunk(0)?

…apache#722) ## What's Changed Allow actually reaching MAX_BUFFER_SIZE at reallocating variable width vectors instead of exceeding it calculating the next power of 2. For unit testing the maximum allocation size has be increased to 2MB - 1byte to simulate the default maximum behavior. Due to this change needed some updates in existing unit tests because of the round ups used at calculating the required buffer sizes. Closes apache#721.
