--- Comment #41 from Avraham Adler <avraham.adler at gmail dot com> --- It has been a few years since the last comment. I recently got hit by this bug for the first time in about a decade and a half of compiling R for Windows 64 using GCC 13.2.0 as packaged in Rtools44 [1]. Does it remain true that the only option to get around this bug without killing all AVX2 is to pass "-Wa,-muse-unaligned-vector-move" when compiling using GCC on Windows 64? Thank you.
