PSA : Android ABB signal 11 (SIGSEGV), code 2 (SEGV_ACCERR)

I was on Unity 2019.1.14 (which for some reason stopped receiving anymore updates for very long time) and not willing to upgrad since I am shipping the game and I don't want to introduce more bugs.

But on building IL2CPP :

- With Android App Bundle : The app close immediately on open with signal 11 (SIGSEGV), code 2 (SEGV_ACCERR) on logcat. Sometimes the app open just fine locally but when you upload to GGP and download back as an internal tester it close immediately on open.
- Just APK : The app open just fine locally except when you upload to GGP and download back as an internal tester, the app close immediately with the same error.

Tried both "Latest" API and Pie API, same result. Delete Library, reimport all, removed all native plugins except Firebase, same result.

Turns out it was fixed by just upgrading to 2019.2.9f1 with no other changes. Wasted 2 days so I guess I could help someone. And I have no time to make a reproduction case.
