  "message": "[memprof] Deduplicate alloc site matches (#142334)\n\nWith:\n\n  commit 2425626d803002027cbf71c39df80cb7b56db0fb\n  Author: Kazu Hirata \u003ckazu@google.com\u003e\n  Date:   Sun Jun 1 08:09:58 2025 -0700\n\nwe print out a lot of duplicate alloc site matches.\n\nThis patch partially reverts the patch above.  The core idea of using\na map to deduplicate entries remains the same, but details are\ndifferent.  Specifically:\n\n- This PR uses the [FullStackID, MatchLength] as the key, where\n  MatchLength is the length of an alloc site match.\n\n- AllocMatchInfo in this PR no longer has Matched because we always\n  report matches.\n\n- AllocMatchInfo in this PR no longer has NumFramesMatched because it\n  has become part of the key.\n\nThis deduplication roughly halves the amount of messages printed out.",
