best memory profiler (to debug accumulated allocation of each line) for D?

[mw]

Hi,

With CPU profiler, we can see the accumulated run time of each 
function & line, I'm wondering if there is such a profiler for 
memory allocation?

The reason I'm asking is because I suspect there are some small 
but repetitive memory allocation going on in the libraries (in C 
and D) I'm using which I do not have control (and no source 
available), but I want to find out where.

I want to run on some test data, and get the memory allocation 
stats for each function (better for each line of code), so I can 
find out where the problem is.

Any suggestions?

Thanks.
