Native crashes lack full stack trace

[markushi]

Integration

sentry-android

Build System

Gradle

AGP Version

newest

Proguard

Enabled

Version

8.32.0

Steps to Reproduce

1. Create a (react native) app with native code

#include <jni.h>

extern "C" JNIEXPORT void JNICALL
Java_com_example_nativeCrash(JNIEnv* env, jobject thiz) {
    // this causes a segmentation fault
    int* ptr = nullptr;
    *ptr = 42;
}

2. Launch the app in release mode, trigger the crashing function on an Android 10 device. (Ensure the required Unwind / Debug Sections (.eh_frame_hdr + .eh_frame) are present

As discussed the culprit most likely is our stack unwinding code not working properly and being unable to extract frames.

Expected Result

A complete stacktrace.

Actual Result

An incomplete stacktrace:

OS Version: Android 10 (QP1A.190711.020.xx)
