commit 19da344403f9d340d7343e99df6ec3e4b79684d9
Author: Kurt Garloff <kurt@garloff.de>

    Trouble is that we don't detect that ARMv7 requires extra buffering
    is md5 input is not properly aligned. gcc-12 apparently is clever enough
    to handle unlaigned memory access for us, which makes us succeed in the
    testcase. It's not clever enough to also succeed in md5_64() :-O
