Observed on go1.24.4 darwin/arm64, the compensation variable is not correctly calculated.

Note you may have to run the tests several times to see it, to get the right ordering of series.

Since the problem went away when I tried to run under the debugger (which disables optimisations), and went away when I added sufficient printf statements (which discourages inlining), I hit upon the idea of disabling inlining for this one function.

See #16714 (comment)

It's going to slow things down a bit, but turns out IsInf is pretty slow already.

Fixes #16714.

It's going to slow things down a bit

should we measure how much slower? if the impact is too large, maybe we can disable the potential inline only for */arm64?

Doesn't show up in the benchmarks. I added sum_over_time(a_X[1d]), where the inner loop calls Kahan.
