[forum:/forumpost/2026-01-08T23:32:19Z|forum post 2026-01-08T23:32:19Z].
The problem is almost certainly harmless since any memory allocation will
be a multiple of 8 bytes, and once the input buffer size gets rounded up to
the next multiple of 8 bytes, the access will still be within bounds.
Nevertheless, it still needs to be fixed.

22c99e01ff Fix the sqlite3-worker1.mjs (ESM, non-bundler) build and have demo-worker1-promiser use that file rather than the vanilla one, as a test case.
