Unable to understand what preconditions for panic that causes crash

[yakovliev-hover]

I have a floating device-specific crash that seems related to ImageNode removing and adding.

Unfortunately, in Logcat I see just

#01 pc 00000000001f8f70 /data/app/~~VLvLN-CzJ_KZFEhcXh3rKQ==/my.application.camera.sample-fTR_y66o22ILsBqjR64BCw==/base.apk!libfilament-jni.so (utils::TPanic<utils::PreconditionPanic>::panic(char const*, char const*, int, char const*, std::__ndk1::basic_string<char, std::__ndk1::char_traits<char>, std::__ndk1::allocator<char> >)+176) (BuildId: 836c96c4fb40776c58fc4d4287f1e7f52dd2041b)

I would like to have more details that can help with troubleshoting.
Maybe someone can suggest how I can achieve more details

There should be more details in the log.

Facing the same issue on Android. I see thousands of crashes in the Google Play Console with the generic "utils::TPanicutils::PreconditionPanic" one liner stack trace, no reason is shown. Also, I can't reproduce these crashes on my Android devices so there is no way to fix them.

Panic.cpp should call android_set_abort_message() so Android developers can see the reason for the crash in the tombstone in either Google Play Console or Crashlytics.

#if defined(__ANDROID__)
#    include <android/set_abort_message.h>
#endif

...

template<typename T>
void TPanic<T>::panic(char const* function, char const* file, int line, char const* literal,
        CString reason) {
    if (reason.empty()) {
        reason = CString(literal);
    }
 
    T e(function, formatFile(file), line, literal, std::move(reason));
 
    // always log the Panic at the point it is detected
    e.log();
 
    // Call the user provided handler
    UserPanicHandler::get().call(e);
 
#if defined(__ANDROID__)
    // Register the full panic message as the tombstone "Abort message:" so that it
    // appears in crash reports collected by Google Play Console and other tools that
    // read tombstones from field devices (which never have access to logcat output).
    android_set_abort_message(e.what());
#endif
 
    // if exceptions are enabled, throw now.
#ifdef __EXCEPTIONS
    throw e;
#endif
 
    // and finally abort if we somehow get here
    std::abort();
}

I just sent a PR to handle this issue #9294
