我有一个创建的 GLib 哈希表：
GHashTable *gmem = g_hash_table_new_full(NULL, NULL, (GDestroyNotify) free_memoryaddresses, (GDestroyNotify)free_metadatarecords);
在 Valgrind 中，我收到以下错误：
==19610== 1 errors in context 2 of 2:
==19610== Invalid free() / delete / delete[] / realloc()
==19610== at 0x40291BE: free (vg_replace_malloc.c:427)

我没有内存泄漏。但是如果我注释掉这两个函数中的行，那么我会得到内存泄漏和（错误摘要：来自 1 个上下文的 1 个错误（抑制：0 来自 0））
void free_memoryaddresses(gpointer a)
{ (void)a;
free(a);
}
void free_metadatarecords(gpointer a)
{ (void)a;
free_metadata_record(a);
free(a);
}
这是我的 Valgrind 命令：
G_SLICE=always-malloc G_DEBUG=gc-friendly valgrind --leak-check=yes --tool=memcheck --track-origins=yes -v ./mytest
我通过存储从 malloc 接收到的指针来获取内存键。
