As the title suggests: I'd like to profile the heap usage of my app - where and when how much memory was allocated. I built RPMs for libunwind and gperftools but tcmalloc's profile output only shows mapped libraries and not - as expected - detailed information about allocations. And yes, I installed the debuginfo-rpm of package, which was a debug build of course. Does anyone have experience or suggestions?

If anyone wonders why: The app basically consists of a SilicaListView that displays 70x70 icons (Image element) for each item and after a few items (dozens, not hundreds) memory usage goes from ~120MB (empty list) to ~300MB and pmap shows a bunch of [anon] blocks of 30MB to 70MB in size and I'd like to figure out where they come from...

Thanks,
