Testing allocators is difficult as bugs may only surface after particular
allocation patterns. The main approach to testing _mimalloc_ is therefore
to have extensive internal invariant checking (see `page_is_valid` in `page.c`
for example), which is enabled in debug mode with `-DMI_CHECK_FULL=ON`.

The main testing is then to run `mimalloc-bench` [1] using full invariant checking
to catch any potential problems over a wide range of intensive allocation bench
marks.
