  "message": "GN: Don\u0027t crash when mutating the list in a foreach.\n\nAvoid a crash caused by mutation of the list being iterated over from inside\nthe foreach loop. This does a full copy of the the iterated list since the\ncode inside can\u0027t mutate the array via the loop variable anyway. Although\ntheoretically slower, this doesn\u0027t seem to have a measurable performance\nregression in practice (we generally iterate over few large lists).\n\nAdds documentation and tests for iteration while mutating the underlying list\nvariable.\n\nBug: 818525\nChange-Id: I221fa230685b8998f5874154cad8d5c655b8006c\nReviewed-on: https://chromium-review.googlesource.com/959228\nCommit-Queue: Brett Wilson \u003cbrettw@chromium.org\u003e\nReviewed-by: Roland McGrath \u003cmcgrathr@chromium.org\u003e\nCr-Original-Commit-Position: refs/heads/master@{#544209}\nCr-Mirrored-From: https://chromium.googlesource.com/chromium/src\nCr-Mirrored-Commit: dcba727e7e8b00cb26c4d797d956d48d2e98371f",
