Реагирует на нативное приложение с ошибками Гермеса с сообщением «SIGSEGV: нарушение сегментации (недопустимая ссылка на память)»

Question

В нашем приложении отслеживания ошибок cra sh я вижу увеличение количества сбоев с "SIGSEGV: нарушение сегментации (недопустимая ссылка на память)". Кажется, они происходят только на Android, а трассировка стека полна libhermes.so.

Эта трассировка стека ничего мне не говорит, и я не нашел ни одного существующего вопроса с той же проблемой. У кого-нибудь есть идеи, где искать причину root для этого? Это ошибка javascript, что Гермес превращается в SIGSEGV? Ошибка в гермесе? Cra sh в одной из используемых нами библиотек?

Stacktrace от одного из сбоев.

попробуйте добавить конфиги hermes, например, в app / build.gradle

apply plugin: "com.android.application"

import com.android.build.OutputFile

/**
 * The react.gradle file registers a task for each build variant (e.g. bundleDebugJsAndAssets
 * and bundleReleaseJsAndAssets).
 * These basically call `react-native bundle` with the correct arguments during the Android build
 * cycle. By default, bundleDebugJsAndAssets is skipped, as in debug/dev mode we prefer to load the
 * bundle directly from the development server. Below you can see all the possible configurations
 * and their defaults. If you decide to add a configuration block, make sure to add it before the
 * `apply from: "../../node_modules/react-native/react.gradle"` line.
 *
 * project.ext.react = [
 *   // the name of the generated asset file containing your JS bundle
 *   bundleAssetName: "index.android.bundle",
 *
 *   // the entry file for bundle generation
 *   entryFile: "index.android.js",
 *
 *   // https://facebook.github.io/react-native/docs/performance#enable-the-ram-format

 *   // See http://tools.android.com/tech-docs/new-build-system/user-guide#TOC-Build-Variants
 *   // The configuration property can be in the following formats
 *   //         'bundleIn${productFlavor}${buildType}'

Answer 2

Hermes - это новый JavaScript движок для ReactNative, который вы "можете" использовать.

Если вы не хотите его использовать, вам нужно выполнить некоторые шаги конфигурации, как описано здесь: https://reactnative.dev/docs/hermes

Вы можете проверить файл android / app / build.gradle , если Hermes включен в вашем приложении. Если да, имейте в виду, что hermes не поддерживает "android -bundles", а только apk-Packages.

Может быть (я только догадываюсь), что вы все еще активировали hermes некоторое время go, но Теперь переключитесь с APK на Android -Bundles.

BTW: Использовали ли вы logcat для получения стековой трассировки? Если нет, пожалуйста, попробуйте. В большинстве случаев это сообщения об ошибках, которые вы не увидите в App-Stacktraces на экране устройства.
