那么有没有办法调试这个并获得哪个行发生段错误？ （我在这里找不到这样的帖子，如果它重复，我会删除它）。 代码本身非常大，所以在这里键入它是不正确的我猜，我只是想知道我是否可以使用backtrace调试代码。
答案 0 :(得分：1)
在我的代码中（用cpp编写）我遇到了一个带有以下backtrace的分段错误：
这显然是从您的测试框架输出的。
虽然它包含了相当多的有用信息，但您将从调试器获得很多更多有用的信息（假设您已使用-g标志编译了测试以进行调试）
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
如果出于某种原因你不能或不想使用调试器，你至少可以从现有的崩溃中获取函数，文件和行信息（再次假设你使用{{1}构建了测试} flag：
