This is due to -fstack-clash-protection now being enabled through
buildflags (it was actually enabled on armhf after amd64 and arm64);
gnutls was rebuilt with it and this reliably causes issues under
valgrind.

The actual cause is a bit unclear at the moment but it definitely
triggers under valgrind.

You can look at the "Really enable -fstack-clash-protection on
armhf/armel?" on debian-arm@ (archive at
https://lists.debian.org/debian-arm/2023/11/msg00015.html ).

(and which I need to catch up since I'm falling being on diving more
into the issue)

On Ubuntu we disabled the flag on armhf at least as a stop-gap.

Best,
