在我们的崩溃跟踪应用程序 bugsnag 中，我看到越来越多的崩溃与“SIGSEGV：分段违规（无效内存引用）”有关。它们似乎只发生在 Android 上，并且堆栈跟踪中充满了 libhermes.so。

这个堆栈跟踪什么也没告诉我，我还没有发现任何存在相同问题的问题。有谁知道在哪里寻找根本原因？hermes变成SIGSEGV是javascript错误吗？爱马仕的错误？我们使用的其中一个库发生崩溃？

来自其中一次崩溃的堆栈跟踪。

Hermes 是您“可以”使用的用于 ReactNative 的新 JavaScript 引擎。

如果你不想使用它，你必须像这里描述的那样做一些配置步骤：https ://reactnative.dev/docs/hermes

如果在您的应用程序中启用了 Hermes，您可以检查您的android/app/build.gradle文件。如果是，请注意，hermes 不支持“android-bundles”，而只支持 apk-Packages。

也许（我只是猜测）您前段时间还激活了爱马仕，但现在从 APK 切换到 Android-Bundles。

顺便说一句： 你用logcat得到你的堆栈跟踪吗？如果没有，请尝试一下。大多数情况下，它会显示您在设备屏幕的 App-Stacktraces 中看不到的错误消息。

请尝试添加爱马仕配置，例如在 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
 *   bundleCommand: "ram-bundle",
 *
 *   // whether to bundle JS and assets in debug mode
 *   bundleInDebug: false,
 *
 *   // whether to bundle JS and assets in release mode

 *
 *   // whether to bundle JS and assets in another build variant (if configured).
 *   // 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}'
 *   //         'bundleIn${buildType}'
 *   // bundleInFreeDebug: true,

 *   devDisabledInStaging: true,
 *   // The configuration property can be in the following formats
 *   //         'devDisabledIn${productFlavor}${buildType}'
 *   //         'devDisabledIn${buildType}'
 *
 *   // the root of your project, i.e. where "package.json" lives
 *   root: "../../",

 *   // where to put drawable resources / React Native assets, e.g. the ones you use via
 *   // require('./image.png')), in release mode
 *   resourcesDirRelease: "$buildDir/intermediates/res/merged/release",
 *
 *   // by default the gradle tasks are skipped if none of the JS files or assets change; this means
 *   // that we don't look at files in android/ or ios/ to determine whether the tasks are up to
 *   // date; if you have any other folders that you want to ignore for performance reasons (gradle
