    But when I don't know the number of possible hits how can I use the API then? Using a large number won't be a guarantee of not crashing.
    The won't fix is nonsensical.

    I am seeing random memory crashes in a release build probably caused by heap corruption. The stack trace is different everytime. This is caused by doing overlapsphere command close to a big pile of physics objects. Confirmed that increasing the results array size fixes the crashing.

    UnityPlayer.dll!block_remove() Unknown
    UnityPlayer.dll!tlsf_free() Unknown
    UnityPlayer.dll!DynamicHeapAllocator::Deallocate(void *) Unknown
    UnityPlayer.dll!DualThreadAllocator<class DynamicHeapAllocator>::TryDeallocate(void *) Unknown
    UnityPlayer.dll!MemoryManager::Deallocate(void *,struct MemLabelId,char const *,int) Unknown

    Reliably crashes whenever any one of the commands in the batch hit more than maxHits colliders.

    Maybe that's intended? It does say "You should adjust maxHits and result array size accordingly to store all hits." Guess I'm setting maxHits to 500. Can't be too safe!

    We experience the same crash with OverlapSphereCommand when there is more results than the maxHits defined when we schedule the job
