Android应用集成HWAddress Sanitizer后启动失败，wrap.sh遭信号11终止

我按照Android官方文档集成HWAddress Sanitizer，运行应用时出现wrap.sh执行失败的情况，进程多次被信号11终止并重复启动。

当前wrap.sh代码 #

#!/system/bin/sh
echo "wrap Running with HWASAN $@"
LD_HWASAN=1 exec "$@"

错误日志输出 #

排查与解决思路 #

信号11是段错误（SIGSEGV），说明进程访问了非法内存地址，针对HWASAN集成场景，可按以下步骤排查：

• 检查设备兼容性：HWASAN要求Android 10（API 29）及以上版本，且设备CPU需支持ARMv8.1-Memory Tagging Extension（MTE）。可通过adb shell getprop ro.product.cpu.abilist64查看CPU架构，确认是否支持MTE。
• 验证NDK版本：确保使用r21及以上版本的NDK，建议用最新稳定版，低版本NDK对HWASAN的支持存在缺陷。
• 调整wrap.sh脚本：部分场景下直接设置LD_HWASAN=1会导致系统进程加载异常，可尝试修改脚本为：

  #!/system/bin/sh
  exec /system/bin/sh -c 'LD_HWASAN=1 exec "$@"' -- "$@"
  

• 确认编译配置：确保所有Native库都用HWASAN编译，混合普通编译与HWASAN编译的库会引发兼容性问题。在gradle中开启HWASAN：

  android {
      defaultConfig {
          externalNativeBuild {
              cmake {
                  arguments "-DANDROID_HWASAN=ON"
              }
          }
      }
  }
  

• 禁用冲突工具：如果同时启用了ASAN等其他内存调试工具，会与HWASAN冲突，需关闭后再测试。
