Note: A new optimization seems to trigger a latent LLVM bug affecting x86-64 (and maybe x86 too) that can lead to miscompilations https://github.com/rust-lang/rust/issues/159035

I would hold off on upgrading anything important.

Oh no. @theemathas's new reproducer is also miscompiling in 1.96

Apparently the bug exists since 1.86 or so
