在 cpp 中使用回溯调试分段错误
Debugging segmentation fault with backtrace in cpp
在我的代码（用 cpp 编写）中，我遇到了以下回溯的分段错误：

那么有没有办法调试这个并在哪一行发生段错误？ （我在这里找不到任何这样的帖子，如果重复我会删除它）。
代码本身很大，所以我想在这里输入它是不正确的，我只是想知道我是否可以使用回溯调试代码。
In my code (written in cpp) I am getting a segmentation fault with following backtrace:
这是（显然）您的测试框架的输出。
虽然它包含相当多的有用信息，但您将从调试器中获得 很多 更有用的信息（假设您已经编译测试以使用 -g 标志).
gdb build/debug/lock_free_list_test
(gdb) run
... wait for SIGSEGV
(gdb) where ## should print file and line info leading to the crash
(gdb) info locals ## should print values of local variables and parameters
如果由于某种原因您不能或不想使用调试器，您至少可以从现有的崩溃中获取函数、文件和行信息（再次假设您已经使用 -g标志）：
addr2line -fe build/debug/lock_free_list_test 0xa053 0x9159 ...
考虑 运行ning valgrind，它记录任何与内存相关的错误的回溯，它可以在 C 和 C++ 上使用。设置 LD_LIBRARY_PATH，将给出确切的问题行。尝试一次 运行 一个测试，因为 valgrind 有时会很耗时，而且构建是否 debug/release 并不重要。我可以看到您在 Linux 64 位上遇到问题，但如果您可以选择使用 Windows，那么内存博士也会有很好的帮助。
在我的代码（用 cpp 编写）中，我遇到了以下回溯的分段错误：

那么有没有办法调试这个并在哪一行发生段错误？ （我在这里找不到任何这样的帖子，如果重复我会删除它）。 代码本身很大，所以我想在这里输入它是不正确的，我只是想知道我是否可以使用回溯调试代码。
In my code (written in cpp) I am getting a segmentation fault with following backtrace:
这是（显然）您的测试框架的输出。
虽然它包含相当多的有用信息，但您将从调试器中获得 很多 更有用的信息（假设您已经编译测试以使用 -g 标志).
gdb build/debug/lock_free_list_test
(gdb) run
... wait for SIGSEGV
(gdb) where ## should print file and line info leading to the crash
(gdb) info locals ## should print values of local variables and parameters
如果由于某种原因您不能或不想使用调试器，您至少可以从现有的崩溃中获取函数、文件和行信息（再次假设您已经使用 -g标志）：
addr2line -fe build/debug/lock_free_list_test 0xa053 0x9159 ...
考虑 运行ning valgrind，它记录任何与内存相关的错误的回溯，它可以在 C 和 C++ 上使用。设置 LD_LIBRARY_PATH，将给出确切的问题行。尝试一次 运行 一个测试，因为 valgrind 有时会很耗时，而且构建是否 debug/release 并不重要。我可以看到您在 Linux 64 位上遇到问题，但如果您可以选择使用 Windows，那么内存博士也会有很好的帮助。
