NDK crash reports silently drops

[artechventure]

Description

NDK crash reports are silently lost. JS and JVM crashes are reported reliably, but NDK crashes (SIGABRT, SIGSEGV) does not appear in Datadog Error Tracking.

Minimal Reproduction

Repo: https://github.com/artechventure/datadog-reactnative-ndk-test

git clone https://github.com/artechventure/datadog-reactnative-ndk-test.git
cd datadog-reactnative-ndk-test
npm install
cp .env.example .env
# Fill in Datadog credentials
npx react-native run-android --mode=release

1. Launch app in release build (debug mode works)
2. Tap "NDK Crash" — app dies
3. Relaunch app
4. Check Datadog Error Tracking — crash does not appear
5. Repeat — NDK crashes are silently lost

JS and JVM crash buttons in the same app report instantly.

(We initially tested with C++ native modules (abort(), null pointer dereference) to trigger real NDK crashes and observed the same result. The Kotlin Process.sendSignal() approach is used here purely for a minimal reproducible project.)
