我有以下崩溃日志和应用程序的完整源代码。
我所看到的只是在调用free时调用libc中的abort（可能是从libstdc ++ delete调用的，甚至没有显示。）如何调试我的问题？有什么想法吗？
我是否可以以任何方式使用pc周围代码中的信息，lr周围的代码或堆栈上的地址来了解有关该问题的更多信息？
可能的原因是什么？

答案 0 :(得分：0)
首先你应该得到libc.so的符号。您可以在“out”目录下找到它。在运行“nm -gCl libc.so”之后，这将打印出lib中的所有符号，以及它们所在的地址。将这些地址与coredump中的地址进行比较，您将能够恢复调用堆栈。崩溃时间。
以下是我在libc.so上获得的一些输出 00021595 T wcswidth bionic / libc / wchar / wcswidth.c：44 00020909 T wcsxfrm bionic / libc / stdlib / wchar.c：305 000208d5 T wctob bionic / libc / stdlib / wchar.c：311 000208e1 T wctype bionic / libc / stdlib / wchar.c：316 000208d9 T wcwidth bionic / libc / stdlib / wchar.c：333 000215c5 T wmemchr bionic / libc / wchar / wmemchr.c:40 000215dd T wmemcmp bionic / libc / wchar / wmemcmp.c：40 00021605 T wmemcpy bionic / libc / wchar / wmemcpy.c:41 00021611 T wmemmove bionic / libc / wchar / wmemmove.c:41
