Wasmtime GitHub notifications bot (Apr 06 2026 at 20:20):alexcrichton opened PR #12976 from alexcrichton:further-tweak-custom-page-sizes to bytecodealliance:main:
This commit adjust the behavior of #12884 to return -1 from
memory.growinstead of trapping when the growth would exceed the maximal allowable size of memory. This fixes a fuzz-bug which had an unexpected trap and upon further reflection this feels more accurate for what custom-page-sizes can do. With a 1-byte-page memories can grow to 4GiB-2 because that means that -1 always means "growth failed".<!--
