--- Comment #33 from Cory Fields <lists at coryfields dot com> ---
Adding another +1. Still present in 10.3.0.
Bitcoin Core's sha2 code uses avx2 when possible. We ran into this bug when
bumping our toolchain:
https://github.com/bitcoin/bitcoin/pull/24736
and opted to take Debian's patch:
https://salsa.debian.org/mingw-w64-team/gcc-mingw-w64/-/blob/master/debian/patches/vmov-alignment.patch
It's unfortunate that the best and most common advice for using avx2 with
gcc/mingw is to use a patched compiler. Might it be possible to accept Debian's
patch upstream?
