I haven't yet been able to find anything at all about this upstream...
It's got to be related to https://github.com/rust-lang/rust/issues/120701. I don't see anything in recent lock_api or memoffset commits.. It looks like memoffset got removed too: https://github.com/rust-lang/rust/commit/28e60de4879786a02c215f83f8ba96f474bcbcaa, which is why 1.75.0 may be fine. matoro do newer versions work?
In your log, there's also: ``` thread 'fatal runtime error: Rust cannot catch foreign exceptions coordinator' panicked at compiler/rustc_middle/src/util/bug.rs:36:26: /rustc/a28077b28a02b92985b3a3faecf92813155f1ea1/compiler/rustc_codegen_ssa/src/back/write.rs:1594:29: worker thread panicked stack backtrace: rustc exited with signal: 6 (SIGABRT) (core dumped) error: could not compile `rustc_driver` (lib) Caused by: Did not run successfully: signal: 6 (SIGABRT) (core dumped) ``` ...
