Memory leaks 读取malloc输出

我有一个用活性分析实现的寄存器分配器，我得到一个seg错误：

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff7560d9d in _int_malloc () from /lib64/libc.so.6

因此，我在valgrind上运行了它，试图通过以下命令查看错误：

valgrind -v --leak-check=yes

我以前从未使用过这个程序，我真的不知道为什么会发生seg故障。我怀疑某处内存泄漏。有人能帮我理解valgrind的成果是什么吗

在我看来，您在编译程序时似乎没有添加调试符号。如果您使用的是GCC，请在编译命令中附加“-ggdb”。例如，如果你写过：

gcc -o program main.c

将其更改为：

gcc -o program main.c -ggdb

然后Valgrind将能够将潜在错误与代码联系起来。另外，我认为您不需要在Valgrind命令中使用“-v”标志

好的，我
