Surely you meant x87 FP instructions? The 486 didn't have SSE instructions.

Probably not 486 - this was 1999-2000 timeframe, so some sort of Pentium thing.
It was definitely the new instructions though, so whatever Intel chip had the new features had this 1 stepping that had this bug (and it wasn’t the first version of the chip either)
