Thanks for this. As you have realised, libc6 is a Debian package that Devuan
uses directly without recompilation so this issue is correctly dealt with in
Debian's BTS.

However, one thought that occurs to me is whether apparmor is causing this? Does
disabling it[1] restore predictable behaviour?

Thanks.
