Assertion failed: dest_begin <= m_size #3701
Description
What happened?
We recently received a lot of crash reports regarding native realm errors. Unfortunately I can't reproduce the errors. But from the logs I can tell that it happens when doing realm.RemoveAll<T>();.
Can you see from the logs what's causing this?
Also it would be good if you translate such native exceptions to managed ones. Otherwise we don't have a chance to handle them gracefully.
Repro steps
Didn't manage to reproduce yet.
