It affects code generated by the OCaml native compiler, which includes the OCaml compiler itself since it is written in OCaml. See also: https://caml.inria.fr/mantis/view.php?id=7452
It also affects code generated by GCC, but apparently GCC is less likely to generate code sequences which trigger the CPU bug.

Possibly, but that was not the issue here. It's clear from your own link that the crashes were due to C code in the OCaml runtime (used by the compiler itself), which is written in C and was compiled with GCC at -O2. See https://caml.inria.fr/mantis/view.php?id=7452#c17129
Indeed, you're right.
