So is there a way to debug this and get on which line segfault occurs? 那么，有没有一种方法可以调试此错误并找出发生在哪条段上的段错误？ (I could not find any posts like this here, if it's duplicate I will delete this). （我找不到任何像这样的帖子在这里，如果是重复的，我会删除此）。 The code itself is pretty big so typing it here would not be correct I guess, I just wonder if I can debug a code with backtrace. 代码本身很大，所以我猜这里键入它是不正确的，我只是想知道是否可以使用backtrace调试代码。

In my code (written in cpp) I am getting a segmentation fault with following backtrace:
This is (apparently) output from your testing framework. （显然）这是测试框架的输出。
While it contains quite a bit of useful info, you will get a lot more useful info from a debugger (assuming you've compiled your test for debugging with the -g flag). 虽然它包含了相当多的有用的信息，你会得到很多来自调试器的更多有用的信息（假设你已经编译了调试测试与-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
If for some reason you can't or don't want to use debugger, you can at least get the function, file and line info from your existing crash (again assuming you've built your test with -g flag): 如果由于某种原因您不能或不想使用调试器，则至少可以从现有崩溃中获取函数，文件和行信息（再次假设已使用-g标志构建了测试）：
addr2line -fe build/debug/lock_free_list_test 0xa053 0x9159 ...

Consider running valgrind which logs the back trace of any memory related errors and it can used on both C and C++. 考虑运行valgrind，该日志记录任何与内存相关的错误的追溯信息，并且可以在C和C ++上使用。 Setting LD_LIBRARY_PATH, would give the exact line of issue. 设置LD_LIBRARY_PATH将给出确切的信息。 Try to run one test at a time as valgrind can be time consuming sometimes and it doesn't matter if the build is debug/release. 尝试一次运行一个测试，因为valgrind有时会很耗时，并且构建是否为调试/发布都没有关系。 I can see that you're having issues on Linux 64bit but if you've an option of using Windows then Dr. memory would be of good help too. 我可以看到您在Linux 64位上遇到问题，但是如果您可以选择使用Windows，那么Dr. memory也将是一个很好的帮助。
