我有一些 Delphi 6 代码使用 New 分配内存并使用 Dispose 释放它。我单步执行了代码，发现 New 和 Dispose 实际上都被调用了。
我想知道为什么 FastMM 报告内存泄漏，即使调用了 Dispose。这可能与正在处理的项目位于 var 部分中的事实有关吗？
type TRunP = record
channels : Word; (* channels for program *)
GCharH : Word; (* Character Height *)
GCharW : Word; (* Character Width *)
... [snip]
end;
...
PRunPBuf = ^TRunP; //record pointer
...
var
ptrRunPBuf: PRunPBuf;
...
New(ptrRunPBuf); //here is the problem, FASTMM claims this was never disposed, but dispose was called without error.
...
Dispose(ptrRunPBuf);
这是来自 FastMM 的信息。
