gdb调试ros node崩溃地址

• 编译Debug版本

catkin_make -DCMAKE_BUILD_TYPE=Debug

• gdb启动ros node

rosrun --prefix 'gdb -ex run --args'  package   node

[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/aarch64-linux-gnu/libthread_db.so.1".

Program received signal SIGSEGV, Segmentation fault.
0x0000000000460d30 in boost::detail::atomic_increment (pw=0x555ed0 <__libc_csu_init+8>) at /usr/include/boost/smart_ptr/detail/sp_counted_base_sync.hpp:43
43	    __sync_fetch_and_add( pw, 1 );

 此时看到 'Segmentation fault'崩溃了，使用'bt'命令列出崩溃call stack

(gdb) bt

这里已经可以都看到frame 6调用shared_ptr引起崩溃，还有代码文件名和行数。接下来可以　frame 6 和 frame info来看详细的寄存器信息.

其它的调试命令如: info locals , info args 等可以打印frame的参数等
