--- Comment #2 from Mikael Pettersson <mikpelinux at gmail dot com> ---
Works with gcc-9.4, ICEs with gcc-10.3 and above. Git bisect identified

# first bad commit: [9b75f56d4b7951c60a656396dddd4a65787b95bc] Apply maximum
nunits for BB SLP

as the cause of the ICEs, though it possibly only exposed a latent target
issue.
