实例化stl映射时android应用程序崩溃 [英] android application crashes when instantiating stl map

问题描述

我一直在尝试使用我在android应用程序中用c ++编写的库，并且该库因非法指令错误而崩溃.我开始注释掉部分代码，直到除了成员变量(stl向量和映射)外什么都没有.所以我尝试直接调用除了创建地图外什么都不做的函数，当我这样做时，android studio中的调试器停止在地图的构造函数中.如果我删除地图并执行其他操作，例如从资产文件夹中读取一些文件，并将其内容作为字符串返回给Java接口，则它可以正常工作.我有办法继续使用c ++映射，因为似乎android c ++运行时实现在这里出错了吗?

I have been trying to use a library I wrote in c++ in an android application and its been crashing with illegal instruction error. I started commenting out parts of the code until nothing was left but member variables which are a stl vector and map. So I try and directly call function that does nothing but create a map and when i did this the debugger in android studio stopped inside the constructor of the map. If i remove the map and do anything else like read some files from asset folder and return their content as a string to java interface it works. Is there a way for me to continue using c++ maps because it seems that the android c++ runtime implementation is at fault here?

A/libc: Fatal signal 4 (SIGILL), code 2, fault addr 0x7f795a502e89 in tid 585

崩溃消息

SIGILL(信号SIGILL:非法指令操作数)

SIGILL (signal SIGILL: illegal instruction operand)

jni代码

extern "C"
JNIEXPORT void JNICALL
Java_com_hasebou_MainActivity_test(JNIEnv *env, jobject instance){

std::map<int,int> hello;
}

Java中的

声明

public native void test();

推荐答案

结果表明启用avx指令会导致此问题，因为android仅支持SSE

Turns out enabling avx instructions caused the problem because android only supports SSE
