When enabled, some delete expressions start using\n\u003e \u003e different version of operator delete() with a size parameter. See\n\u003e \u003e https://en.cppreference.com/w/cpp/memory/new/operator_delete for details\n\u003e \u003e on delete operators being used.\n\u003e \u003e\n\u003e \u003e The size information can be used for performance improvement in memory\n\u003e \u003e allocator or bug detection mechanism like ASan. This CL enables the flag\n\u003e \u003e on ASan builds to help ASan catch size-mismatch errors.\n\u003e \u003e\n\u003e \u003e This CL also updates abseil exported symbols for Win ASan builds. Sized\n\u003e \u003e deallocation can not be activated on other build configurations on\n\u003e \u003e Windows at this moment.\n\u003e \u003e\n\u003e \u003e Original patch: https://crrev.com/c/6304218\n\u003e \u003e\n\u003e \u003e Bug: 345541122, 410190984, 410192659\n\u003e \u003e Change-Id: Ie046a61ffd9fcdcb033e3787deeeede511e0dc93\n\u003e \u003e Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/6445033\n\u003e \u003e Commit-Queue: Mikihito Matsuura \u003cmikt@google.com\u003e\n\u003e \u003e Reviewed-by: Nico Weber \u003cthakis@chromium.org\u003e\n\u003e \u003e Cr-Commit-Position: refs/heads/main@{#1446230}\n\u003e\n\u003e Bug: 345541122, 410190984, 410192659\n\u003e No-Presubmit: true\n\u003e No-Tree-Checks: true\n\u003e No-Try: true\n\u003e Change-Id: I5353e399fcac98df23db4b8f246f487b4fb4109f\n\u003e Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/6449096\n\u003e Reviewed-by: Nico Weber \u003cthakis@chromium.org\u003e\n\u003e Bot-Commit: Rubber Stamper \u003crubber-stamper@appspot.gserviceaccount.com\u003e\n\u003e Commit-Queue: Nico Weber \u003cthakis@chromium.org\u003e\n\u003e Auto-Submit: Mikihito Matsuura \u003cmikt@google.com\u003e\n\u003e Cr-Commit-Position: refs/heads/main@{#1446323}\n\nBug: 345541122, 410190984, 410192659\nChange-Id: Ie1bfd7e33499aee65f28d06d9c37ffa17365d401\nReviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/6450840\nBot-Commit: Rubber Stamper \u003crubber-stamper@appspot.gserviceaccount.com\u003e\nCommit-Queue: Mikihito Matsuura \u003cmikt@google.com\u003e\nReviewed-by: Nico Weber \u003cthakis@chromium.org\u003e\nCr-Commit-Position: refs/heads/main@{#1447665}\nNOKEYCHECK\u003dTrue\nGitOrigin-RevId: e1f5df996cacb8b8f8eefe8fb7029fbb4c0acfb0\n",
