> Just before that line, PageReader.next() calls the following method:
> {noformat}
> private void allocatePageData(int size) {
> Preconditions.checkArgument(pageData == null);
> pageData =
> parentColumnReader.parentReader.getOperatorContext().getAllocator().buffer(size);
> }
> {noformat}
> this method should check the output of BufferAllocator.buffer(int) to make
> sure the buffer was successfully allocated.
