Debugging memory leaks

[Hipreme via Digitalmars-d-learn]

I want to know if there is some way to debug memory leaks in 
runtime.

I have been dealing with that by using a profiler and checking D 
runtime function calls. Usually those which allocates has high 
cpu usage so it can be easy for those bigger ones. While for the 
smaller ones, this approach doesn't seem to work and looking into 
my task manager I can see it increasing the memory usage very 
slowly.

I wanted to know if there is an option to do that on RUNTIME. 
--vgc is not a good option as I don't care about allocations that 
happens on initialization code.
