runtime: Mono crashes with SEGV_ACCERR for P/Invoke in android Debug

This blocks migration from Xamarin to net6.0-android. Although it may not be Mono’s fault, it definitely requires help from Mono developers.

Configuration

A net6.0-andoid project using the Realm package. In DEBUG configuration, it crashes during initializing native interop for Realm. I tried different combinations, but it always works in Release and crashes in Debug.

Logcat crash information is like this:

The patterns realm is doing P/Invoke can be found here.

Build Realm is quite complicated, and it has only netstandard configuration. Is there any thing obviously wrong?

It is likely not a stack overflow, as it also crashes in a simpler project.
