多线程发生内存踩踏的时候，发生coredump的堆栈往往在其他代码段，不能准确通过coredump堆栈找到内存踩踏的实际位置，这个时候如何准确抓取到发生内存踩踏的代码段，有哪些推荐工具可以使用：

Here are some strategies and tools to help you accurately capture the code segment responsible for the memory stomping:

1. Enable AddressSanitizer (ASan) or similar tools: * ASan is a memory error detector that can help identify memory stomping issues. * Compile your program with ASan enabled (e.g., -fsanitize=address in GCC or Clang). * When a memory stomping issue occurs, ASan will report the problematic memory access and provide a more informative error message.

2. Use a memory debugging tool like Valgrind: * Valgrind is a memory debugging and profiling tool that can help identify memory stomping issues. * Run your program under Valgrind (e.g., valgrind --tool=memcheck ./myprogram). * Valgrind will report
