Note that this is a confusing one, since the officially published source code that Apple claims is being run does not have this bug (apple-oss-distributions/libplatform@main...rel/libplatform-349), but is also very clearly not the code that is actually present in libsystem_platform.dylib via disassembly, which is mostly similar but has more pointer authentication code. That code is APSL licensed, so Apple can do whatever they want there, just confusing to have them seemingly intentionally misrepresent which code is being used. And it just happens to be in our favor, performance-wise, to disable executing the buggy function. |

Hey folks, just saw this issue after experiencing ericphanson/LicenseCheck.jl#11 (comment) on Julia 1.10.10 -- Will this be backported to 1.10 as well? Thank you! |

This doesn't backport cleanly to 1.10. @vtjnash Can you do a manual backport? |
