title: track C++ memory allocations
body: <p>I am looking for a way to track memory allocations in a C++ program. I am <em>not</em> interested in memory leaks, which seem to be what most tools are trying to find, but rather creating a memory usage profile for the application. Ideal output would be either a big list of function names plus number of maximum allocated bytes over time or better yet, a graphical representation of the heap over time. Horizontal axis is time, vertical axis heap space. Every function would get it's own color and draw lines according to allocated heap bytes. Bonus points for identifying allocated object types as well.</p>
  
  <p>The idea is to find memory bottlenecks/to visualize what functions/threads consume the most memory and should be targetted for further optimization.</p>
  
  <p>I have briefly looked at Purify, BoundsChecker and AQTime but they don't seem to be what I'm after. Valgrind looks suitable, however, I'm on Windows. <a href="http://www.almostinfinite.com/memtrack.html" rel="noreferrer">Memtrack</a> looks promising, but requires significant changes to the source code.</p>
  
  <p>My google skills must have failed me, cause it doesn't seem to be such an uncommon request? All the needed information to create a tool like that should be readily available from the program's debug symbols plus runtime API calls - no?</p>
