There were a few places that still checked against the limit for initial memory size rather than the limit for memory size after growth (which was recently separated from the former). Bug: v8:7881 Change-Id: Id17d86e2f7a5dfa4f1dd35153b0cefc01f72ed33 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2078574 Commit-Queue: Jakob Kummerow <jkummerow@chromium.org> Reviewed-by: Andreas Haas <ahaas@chromium.org> Cr-Commit-Position: refs/heads/master@{#66496}
