dynaTrace has a great solution for memory diagnostics. It wont tell you which method allocated how much memory - but - it will tell you which objects are responsible for your out-of-memory exceptions.
After you have identified which objects are a problem and "who" keeps them alive you can go one step further and define "Memory Sensor Rules" - they will show you memory allocations for specific classes along the PurePath.

Best is to start with the following webinar that explains the memory diagnostics process step-by-step: dynaLearn Webinar - Memory and Thread Diagnostics - February 15, 2012

I'd like to also add this page from the documentation, which I used yesterday to help someone determine the exact cause of a memory leak by walking through step-by-step what was done in the document.
