> The `attempt_allocate_memory_at(addr, size)` may fail for some reasons that `::mmap`  will report. To find out why an attempt failed, an `int *` is passed down deep to the `::mmap` to return the `ERRNO` back to the callers.
> This error code is used in gTest test case to show a proper message.
> 
> The changed test case never failed after 10K+ repetitions, but in case it happens in future the reason is also printed out.
