c++ - 运行良好，但在完成之前崩溃

<分区>

我用 OpenCV 和 boost 用 c++ 编写了一个应用程序，它运行良好且正确，但在退出之前它崩溃了(如果我逐步调试，当 return 0; 在main) 结尾说:

在 kdevelop 中:

*** Error in `/home/xxx/git_repos/my_proj/build/my_proj': free(): invalid pointer: 0x00000000008939c0 ***
*** Crashed with return code: 0 ***

在命令行中:

*** Error in `./my_proj': free(): invalid pointer: 0x00000000008939c0 ***
Aborted (core dumped)

如果我使用 gdb:

[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
*** Error in `/home/xxx/git_repos/my_proj/build/plate_info_extractor': free(): invalid pointer: 0x00000000008939c0 ***

Program received signal SIGABRT, Aborted.
0x00007ffff5b83cc9 in __GI_raise (sig=sig@entry=6) at ../nptl/sysdeps/unix/sysv/linux/raise.c:56
56  ../nptl/sysdeps/unix/sysv/linux/raise.c: No such file or directory.

有什么帮助吗？我不知道哪里出了问题。

我已经评论了一些代码部分，看来问题出在我用来记录错误/信息的代码中......所以:
