当我打开由我的软件创建的核心文件时，我看到：

 0x0000000800d2afc7 in g_slice_set_config () from /usr/local/lib/libglib-2.0.so.0
 0x0000000800d2b21b in g_slice_set_config () from /usr/local/lib/libglib-2.0.so.0
 0x0000000800d2b703 in g_slice_free1 () from /usr/local/lib/libglib-2.0.so.0
 0x00000000004a027d in user_free (user=0x859945bc0) at user/user.c:178

 0x000000000049e865 in dpi_exit () at dpi.c:465

 0x0000000000414569 in main (argc=5, argv=0x7fffffffebc0) at itap.cpp:463

我在项目中熟悉的代码是user_free. 内部user_free：

 static inline void
 user_free(dpi_user_t *user)
 {
    if (user->policy)
        policy_rem_ref(user->policy);
    user_remove(user);
    g_slice_free(dpi_user_t, user);
 }

当我打印可疑指针时：

 (gdb) print user
 $5 = (dpi_user_t *) 0x859945bc0
 (gdb) print user->policy
 $6 = (rbpe_policy_t *) 0x80b1acc20

因为核心发生在一个自由函数中，所以我想到的只有空指针访问。但是当我检查指针时，它们根本不为空。各位大佬知道可能是什么原因吗？
