Reading the test case, the context is requesting that the kernel be executed in smaller chunks. And inspecting the value in a debugger, the result is now a ChunkedArray. So it seems before, the output was preallocated and now it is not. The reason relates to my question above - why does `can_write_into_slices` disable preallocation? If `true`, what is expected to happen is that the output will be allocated all at once, and the kernel will be executed on small slices of the input, writing into slices of the output. But that breaks down if we prevent preallocation. -- This is an automated message from the Apache Git Service.
