在我们的崩溃跟踪应用程序bugscang中，我看到越来越多的崩溃与"SIGSEGV:分段冲突(无效内存引用("有关。它们似乎只在安卓系统上发生，并且stacktrace中充满了libhermes.so.
这个堆叠竞赛告诉我什么都没有，我也没有发现任何存在相同问题的问题。有人知道在哪里可以找到造成这种情况的根本原因吗？是不是一个javascript错误导致hermes变成了SIGSEGV？爱马仕的虫子？我们使用的某个库发生故障？
其中一个崩溃的Stacktrace。

Hermes是ReactNative的一个新的JavaScript引擎，您"可以"使用它。
如果你不想使用它，你必须做一些配置步骤，如下所述：https://reactnative.dev/docs/hermes
如果您的应用程序中启用了Hermes，您可以签入android/app/build.gradle文件。如果是，请注意，爱马仕不支持"android捆绑包"，而只支持apk软件包。
也许(我只是猜测(你前段时间还激活爱马仕，但现在从APK切换到Android Bundles。
BTW:您是否使用logcat获得堆叠竞赛？如果没有，请尝试一下。大多数时候，它会在设备屏幕上显示你在应用程序堆栈跟踪中看不到的错误消息。
请尝试在app/build.gradle 中添加hermes配置
