Android Oreo 8.0 Native C ++崩溃:无效的pthread_t传递给libc [英] Android Oreo 8.0 Native C++ crash: invalid pthread_t passed to libc
问题描述
我有一个使用Cmake将本机代码编译到我的应用程序中的Android应用程序，它在运行Android 7.1的Pixel设备上运行良好.我决定将我的Pixel设备升级到Oreo 8.0，现在我无法在我的应用程序中输入本机C ++代码.
I have an Android Application that uses Cmake to compile native code into my application, and it was working great on A Pixel device running Android 7.1. I decided to upgrade my Pixel device to Oreo 8.0 and now I cannot enter the native C++ code in my app.
这是崩溃时的logcat转储:

这是添加共享库的Cmake代码
Here is the Cmake code that adds the shared library
add_library(NativeLib SHARED IMPORTED)
set_property(TARGET NativeLib PROPERTY IMPORTED_LOCATION "${PROJECT_SOURCE_DIR}/NativeLib/Android/Release/${ANDROID_ABI}/libNativeLib.so")
共享库然后链接到目标.
The shared library then gets linked to the target.
正如我所说，这一切都在Android 7.1上完美运行，并将设备升级到8.0导致了崩溃，这是一个新的错误吗?我确实在这里 https:上阅读了8.0的本地库"更改.//developer.android.com/about/versions/oreo/android-8.0-changes.html .
As I said, this was all running flawlessly on Android 7.1 and upgrading the device to 8.0 caused this crash, is this a new bug? I did read the "Native Libraries" changes for 8.0 here https://developer.android.com/about/versions/oreo/android-8.0-changes.html.
我还在我的图书馆上运行了readelf并把它取回来，这对于8.0来说还可以:
I also ran readelf on my library and got this back, which looks okay for 8.0:

有什么想法吗?谢谢！
推荐答案
问题出在 __ pthread_internal_find 函数中.
在Android 8.0之前，如果在线程列表中找不到线程，则仅返回nullptr.但是，在Android 8.0中，将会发生致命事故.
Before Android 8.0, if no thread can be found in the thread list, just a nullptr is returned. However, in Android 8.0, a fatal will be made.
无论如何，这需要更仔细地处理POSIX内容...
This is requiring more careful handling of the POSIX stuff anyway...
请参见 pthread_internal.cpp 供参考.
