Valgrind 中包含的 Memcheck 工具可以檢查以下的程式錯誤：

　　使用未初始化的記憶體 (Use of uninitialised memory)
　　使用已經釋放了的記憶體 (Reading/writing memory after it has been free’d)
　　使用超過malloc分配的記憶體空間(Reading/writing off the end of malloc’d blocks)
　　對堆疊的非法訪問 (Reading/writing inappropriate areas on the stack)
　　申請的空間是否有釋放 (Memory leaks – where pointers to malloc’d blocks are lost forever)
　　malloc/free/new/delete申請和釋放記憶體的匹配(Mismatched use of malloc/new/new [] vs free/delete/delete [])
　　src和dst的重疊(Overlapping src and dst pointers in memcpy() and related functions)
　　重複free
其他情況還不清楚，等待後續新增
