>To fix bugs, sure. Maybe your program worked due to the bug they fixed.

  Extremely unlikely. CPU bugs generally halt the CPU or fail to write the result or something like that. The Pentium FDIV bug where it would give a plausible but wrong result was a once in a lifetime thing.

    Spectre and Meltdown exploits stopped working, too. Some of them on some CPUs, anyway.
    • lmm 2y ago
      Sure. But those were obviously exploits from the start. You wouldn't write code like that accidentally.

    Do a web search for rdrand and systemd.

        The other guy said "Maybe your program worked due to the bug they fixed.". The RDRAND fix achieved exactly that.
