Commit SHA: 32c65a1d (probably)

This issue shows differences in Release vs. Debug build run of short self-test on Mac M4, OS version 15.6.1, Apple Clang 16. This was discussed in IVAS conformance call on Monday September 22nd.

This is the issue for OSBA format. Some larger differences with maximum being 1220.
