如何分析GDB的coredump文件.

How to analyse a coredump file of GDB.

推荐答案

GDB可以帮助您入门:

GDB can get you started:

$ gdb --help
This is the GNU debugger.  Usage:

    gdb [options] [executable-file [core-file or process-id]]
    gdb [options] --args executable-file [inferior-arguments ...]

[snip extended docs]

因此，您将像这样调用它:

So, you'll invoke it like this:

gdb myprog core

然后，GDB将以通常的方式启动，但是状态就好像您已在断点处停止一样.然后，您可以使用打印"，检查"，列表"，回溯"，向上"，向下"等调查导致崩溃的原因.

GDB will then start in the usual way, but the state will be as if you'd stopped at a breakpoint. You can then use "print", "examine", "list", "backtrace", "up", "down", etc. to investigate what caused the crash.

实际上，您可以使用任何GDB命令，但"continue"，"step"，"next"或其他需要实际运行的程序的命令除外.

In fact, you can use any GDB command except "continue", "step", "next", or anything else that requires an actual running program.
