@pcmoritz Maybe here is the problem. In [`dlmalloc_set_footprint_limit`](https://github.com/apache/arrow/blob/master/cpp/src/plasma/thirdparty/dlmalloc.c#L5367), the input memory is changed by `granularity_align(bytes)` and save to `gm->footprint_limit`. In this case, 1000 bytes will be changed 131072 and 1000000000 will be changed to 1000079360. Therefore, when we try to allocate an object which makes `footprint` between the input limit and the aligned limit, `dlmemalign` may return a normal pointer but [the eviction policy check](https://github.com/apache/arrow/blob/master/cpp/src/plasma/eviction_policy.cc#L73) fails and Plasma crashes.
