It appears to be
===
commit 1c4e8a96cd695c03ff85299bf2392476feae99bb
Author: François Dumont

libstdc++: Fix unordered containers move constructors noexcept qualification

_Hashtable move constructor is wrongly qualified as noexcept(true) regardless
of
_Equal and _H1 copy constructor qualifications.
_Hashtable allocator-aware move constructor is missing its noexcept
qualification like the depending unordered containers ones.

This backport also includes the changes from r11-8062.
===

And also confirmed on x86_64, aarch64, and aarch32.

Btw, 10.3.0 bootstrapped fine for me (but using --with-cpu=power8
--with-tune=power9 just in case that makes a diference).

How did you configure?

The failures shown were on a power 8 LE system for
