例如:set variable = value。 12. 监视变量:使用"watch"命令可以监视指定变量的值,当该变量的值发生改变时,程序会停下来。 13. 查找内存泄漏:使用"leak-check"命令可以检测程序中的内存泄漏。 14. 跟踪系统调用:使用"catch syscall"命令可以跟踪程序中的系统调用。 15. 显示寄存器:使用"info registers"命令可以...

gdb调试方法说明（GDB debug method instructions）GDB debugging essence and examples List of column files 1.List (GDB) list, Line1, line2 Two: executive procedure To run the program for debugging, you can use the run command, behind it can follow to any of the parameters of the program, ...
Also, the ability to view variable values while the target is running eliminates the need to have a physical feedback mechanism such as a blinking LED. The user can simply monitor a variable value and check for changes while the target is running to check if a particular section of code ...
So now you know how to debug segmentation faults with gdb. This is extremely useful (I use it more often then I care to admit). The example also illustrated another very important point: ALWAYS CHECK THE RETURN VALUE OF MALLOC! Have a nice day....
(2)gdb的MALLOC_CHECK_ (3)mtrace和systap 六、core文件配合gfb 七、Valgrind (1)使用未初始化内存 (2)内存泄漏 (3)两次释放内存 (4)使用已经释放的内存 (5)不匹配使用new/delete或new[]/delete[] 八、nm、ldd、objdump 九、使用linux的GDB打印STL 容器 一、基础调试 eg:my_course/course/gdb_study/tes...
