Context

The debug build system supports Valgrind memcheck for memory error detection. Massif (Valgrind's heap profiler) would complement this by providing memory usage snapshots during benchmarks, helping identify allocation hotspots and memory growth patterns.

Proposal

Add make massif-test target that:

  1. Runs selected benchmark tests under valgrind --tool=massif
  2. Outputs .massif files to build-debug/
  3. Optionally runs ms_print for text-based visualization
