Fastmm with New and Dispose Delphi 6

I have some Delphi 6 code that allocates memory using New and frees it using Dispose. I have stepped through the code and see that both New and Dispose actually do get called.

I am wondering why FastMM is reporting a memory leak, even though Dispose is called. Could it be related to the fact that the item being disposed is in the var section?

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);   

Here is the information from FastMM.
