在 gdb 中输入命令frame 15"后，我得到:

Upon entering the command "frame 15" in gdb I get:

(gdb) frame 15
#15 0x0000000000404846 in main (ac=4, av=0x7fff93a31d48) at kprank_new3_norm.cpp:577
577 fout3.close();

谁能帮我弄明白这个?

非常感谢大家.

推荐答案

看起来您正在对已删除或无效/损坏的内容调用 delete 或 free.

It looks like you're calling delete or free on something that has either already been deleted or is invalid/corrupt.

如果原因在您已有的堆栈跟踪中不明显，请尝试在 valgrind 下运行.

Try running under valgrind if the cause isn't apparent from the stack trace you already have.
