SIGSEGV (Segfault) in sentry__value_new_addr / __vsnprintf_chk on Android #4830
Description
Integration
sentry-android
Build System
Gradle
AGP Version
8.12.0
Proguard
Enabled
Version
8.23.0
Steps to Reproduce
- Download TomTomApp from the playStore.
- Integrate sentry-android and/or sentry-android-ndk in the app.
- Run the app on an arm64 device.
- A native crash occurs and Sentry attempts to capture it.
- Instead of capturing, Sentry itself crashes with SIGSEGV during signal handling.
This was first observed in production.
Example of latest 3 logs attached:
sentry.logcat.zip
sentry.logcat(1).zip
sentry.logcat(2).zip
SIGSEGV: Segfault ?, in __vfprintf ?, in vsnprintf ?, in __vsnprintf_chk File "stdio.h", line 82, in _ZL8snprintfPcU17pass_object_size1mPKcz File "sentry_value.c", line 1180, in sentry__value_new_addr ... (140 additional frame(s) were not displayed)
Expected Result
Sentry should handle and capture the native crash, report it to Sentry.io, and not crash during its own signal handling.
Actual Result
Stacktrace appearing under the sentry issue:
