Thanks for letting me know. I've looked into upstream issues/fixes for 
this problem and it seems that these aarch64 test failures are a known 
issue [1]. This bugreport mentions build failures in dune-common's 
Debian package, which nowadays seems to be patched to disable the 
failing tests [2].

[1]: https://gitlab.dune-project.org/core/dune-common/-/issues/262
[2]: 
https://sources.debian.org/src/dune-common/2.9.0-2/debian/patches/disable-long-double-eigenvalue-checks.patch/

I've prepared a patch to apply Debian's patch for disabling the failing 
tests to our dune-common package. You can find it attached to this 
email. Can you test if it fixes the aarch64-linux builds (I don't have 
access to an aarch64 machine)?
I hope that this would also fix the build failures for the other dune-* 
packages on aarch64-linux, which are currently all failing because they 
depend on the broken dune-common package.

Kind regards,
Felix
