Error with Rethink quitting
Hello, I have noticed when using Rethink on my WiFi connection that after a while my Internet starts to fail so I just press on "Stop" to restart WireGuard and DNS and then the app quits on error. I have noticed this doesn't happen on mobile data.
Thanks for your help.

Thanks. This is Android crashing our app (as a security measure, since it has detected some memory corruption).
- #962
We use gomobile and other dependencies which looks suspect but because of the terse crash logs generated by Android on such crashes, we haven't really figured out just why these happen.
Curiously, we request Android to not crash the app on memory corruption, but it still does:

Since v055o, Rethink aggressively opts out of memory tagging. This is a temporary measure and one enforced on us by the Go runtime (especially, cgo; used by our network engine firestack) which doesn't seem compatible with memory tagging, just yet.
