段错误 (核心已转储)

问题原因：

cmake编译选项的问题

解决办法：

将cmake命令更改至如下：

cmake     -DBUILD_WITH_MARCH_NATIVE=ON    -DUSE_PANGOLIN_VIEWER=ON     -DUSE_SOCKET_PUBLISHER=OFF     -DUSE_STACK_TRACE_LOGGER=ON     -DBOW_FRAMEWORK=DBoW2     -DBUILD_TESTS=ON ..

如果还会段错误，尝试将-DBUILD_WITH_MARCH_NATIVE=ON替换成-DBUILD_WITH_MARCH_NATIVE=OFF,然后重新编译
