I'm trying to find the segmentation fault in a c file that is used by an executable but I haven't found any leads. Does anyone know how to do this?

推荐答案

运行gdb并从gdb运行程序，然后使用backtrace.您将获得堆栈框架，您可以通过fram命令遍历该框架，并使用print检查变量的值.通过互联网查看gdb tips \ docs.您可以使用gdb加载由崩溃程序生成的已经存在的核心文件，以查找发生问题的位置.加载的核心文件等于崩溃点的状态，您只需使用backtrace.

Run gdb and run your program from gdb, then use backtrace. you 'll get stack frame, which you can walk through by fram command and use print to check variables' values. Check gdb tips\docs over internet. You can use gdb to load already existing core file, generated by crashed program, to find spot where problem occured. Loaded core file is equal to state at crash point, you just usebacktrace.
