[Android] Native crash (SIGSEGV) on app startup

I tried to integrate sonar into the app that I work on. On some phones with version 0.0.5 and 0.0.8, I noticed a crash in the native part of the code right on the app startup. It’s so quick that I’m not able to even get to the main activity or any point where I can attach the debugger.

Unfortunately, this does not reproduce 100% of the times on all phones. When you hit this, the only available option for me was to disable sonar. Uninstalling and reinstalling the app did not help. I was able to reproduce it on a Nexus 6P and a Google Pixel 2.

I’m attaching the stack trace below, I am not sure if it’s entirely helpful or if it points to the actual problem or not. Let me know if there is any debug option I can turn on to provide more useful logs.

Thank you.

I still get this on 0.9.0+

@passy, I upgraded our dependency to 0.0.9, and it seems to be working fine on both Nexus 6P and Pixel 2. We don’t see any native crashes on startup. The crash was not a 100% repro on the 6P, so I’ll keep an eye out if it re-appears.

Thank you so much for updating OpenSSL – seems to have done the trick!
