Sentry.init()

See https://github.com/getsentry/sentry-react-native/blob/6.0.0/samples/react-native/src/App.tsx#L47

Steps to Reproduce

1. Run the Sentry sample app on Android
2. Observe the app crashing after a few interactions (emulator) or immediately (on an actual device).

Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0xf9ffffffffffd0 in tid 28855 (pool-2-thread-1), pid 28724 (ctnative.sample)

  Package [io.sentry.reactnative.sample] reported as REPLACED, but missing application info. Assuming REMOVED.

3. Disable profiling by commenting out the profilesSampleRate
4. Run the app and verify that there is no crash.

Expected Result

No crash with profiling enabled

Actual Result

The app crashes when profiling is enabled.

Notes

• The issue was introduced with the sample apps upgrade to 0.75.4 Chore: Upgrade sample and E2E tests to RN 0.75 #4155
• A reanimate bug which had a similar stack trace was investigated but upgrading to the latest version (or removing the library) didn't solve the issue.

[antonis]

Noting that I wasn't able to reproduce the crash with a basic RN 0.75.4 RN app with profiling enabled.

Project setup

npx @react-native-community/cli init AwesomeProject --version 0.75.4
cd AwesomeProject
npx @sentry/wizard@latest -i reactNative

Set newArchEnabled=true in android/gradle.properties

Sentry initialisation

Sentry.init({
  ...
  tracesSampleRate: 1.0,
  profilesSampleRate: 1.0,
});

Adding the ndk-stack of the investigated crash:

(offset 0x42b8000) (BuildId: db078b0afc73e2129f8850376d84ff09ee5dcf01)

/__w/react-native/react-native/packages/react-native/sdks/hermes/lib/VM/Profiler/SamplingProfilerPosix.cpp:228:21

The above would indicate that the error occurs in profiler sampling of the latest Hermes.
Changing the Sentry profiler sampling we notice that:

• disabling the platform profilers didn't make a difference
• Reducing the sample rate (e.g. profilesSampleRate: 0.1) seems to hide the issue
