Using auto_vec rather than vec for means the vectors are release

Indeed.
This is actually Jan's original suggestion
https://gcc.gnu.org/pipermail/gcc-patches/2024-June/655600.html which I
improvised on by also using embedded storage. I think it should fix this
regression:

I could not reproduce it on x86-64 linux, so if someone could help me
test it on aarch64 that would be much appreciated.
OK.
Pushed. Sorry for the noise.
Thanks,
Jørgen
