seems the recent change [1] to KahanSum handling causes a test failure

Interesting; I also saw that failure with my latest local build on macOS
aarch64 against Clang trunk. (But didn't debug it further and wrote it
off as maybe some intermittent Clang trunk bug.)
someone on IRC reported the same issue, also from macOS I believe
So, wild speculation, maybe it's a difference between x86-64 and all
other architectures, given how that
<https://gerrit.libreoffice.org/c/core/+/156253/> "Resolves: tdf#156985
Treat adding two KahanSum differently" kept failing for (32-bit)
<https://ci.libreoffice.org/job/gerrit_windows/> up until patch set 7.
(And where patch set 8 reverted back to the original code for _WIN32,
maybe in a misguided attempt to fix something that was seen failing on
Windows 32-bit x86, but not known to (not) fail on Windows x86-64.)
Eike, any thoughts?
