…hearth Deploy time travel Since not only commits to the master branch, but also tags and the beta branch are deployed, we have to be cautious which version of the deploy script is used. GHA always runs the workflow that is commited on the `ref`, that gets tested. For tagged commits. this is 6 weeks outdated workflows/scripts. To prevent this, this workflow first checks out the deploy.sh script, the website templates and all python scripts generating files for the website. changelog: none

…ednet,flip1995 Switch CI to new metadata collection r? `@xFrednet` Things we have to keep in mind: - This removes the template files and the scripts used for deployment from the checkout. This was added in rust-lang#5517. I don't think we ever needed those there. Not sure though. - ~~As a result, we can't remove the python scripts yet. We have to wait until this hits a stable Clippy release.~~ I'll just break the next stable deploy and do it by hand once. - This should be merged together with rust-lang#7279. Me and `@xFrednet` will coordinate the switch - ...? I still have to try out some things: - [x] Is it worth caching? Yes - [x] ~~Is it worth to do a release build?~~ Nope - [x] Does it actually work? With a few changes, yes - [ ] ...? changelog: Clippy now uses a lint to generate its documentation 🎉

Issue: The compiler crashes (SIGSEGV, SIGABRT, etc). Use I-ICE instead when the compiler panics.
Found this while attempting to reproduce #3039. This code crashes:
This is as minimal as I can make it. Removing the second clause of the
||
makes it not crash. Changing the||
to a&&
makes it not crash.The backtrace is:
It crashes where it is trying to read
(*a).header.ref_count
becausea
is a null pointer.The text was updated successfully, but these errors were encountered:
