…inter, r=<try> make writes_through_immutable_pointer a hard error This turns the lint added in rust-lang#118324 into a hard error. This has been reported in cargo's future-compat reports since Rust 1.76 (released in February). Given that const_mut_refs is still unstable, it should be impossible to even hit this error on stable: we did accidentally stabilize some functions that can cause this error, but that got reverted in rust-lang#117905. Still, let's do a crater run just to be sure. Given that this should only affect unstable code, I don't think it needs an FCP, but let's Cc `@rust-lang/lang` anyway -- any objection to making this unambiguous UB into a hard error during const-eval? This can be viewed as part of rust-lang#129195 which is already nominated for discussion.

We have one
That's on them for adding `deny(renamed_and_removed_lints), they are basically asking to have breaking changes. 🤷 The rest seems spurious. :) @bors r=compiler-errors |

Let's try rerunning crater to see if the strange spurious errors reproduce. @craterbot run mode=check-only crates=https://crater-reports.s3.amazonaws.com/pr-129199/retry-regressed-list.txt p=1 |

completed jobs 0/0 fascinating ... 🤔

https://crater-reports.s3.amazonaws.com/pr-129199-1/full.html shows there were 24 crates tested... so probably just a bug in the queue display? |

After completion we clean up the database entries, so 0/0 is expected. |
