ice.log

[matthiaskrgr]

Weird, so as far as I understand, we use beta to build stage 1 and then use stage 1 to build stage 2 and then use stage 2 or 1 to build ra (in bootstrap) which ICEs, but i was not able to reproduce this by compiling hir-ty inside the ra git repo directly with nightly/master :/

[albertlarsan68]

Maybe the fail will manifest tomorrow ?

[matthiaskrgr]

Hmm I am able to reproduce this in the rust-analyzer repo with -Zmir-opt-level=5 or 4, I thought that "3" was the default when doing a --release build but perhaps I'm wrong there...

[matthiaskrgr]

I tried to minimize with cargo-minimize but it threw an error while doing so :/

I tried to minimize with cargo-minimize but it threw an error while doing so :/

a panic? if so you can probably fix it by staring very closely at the cursed "path" code from cargo-minimize and figuring out which AST nodes aren't yet counted and leads to duplicate paths.

[matthiaskrgr]

No panic (/stacktrace) by c-minimize, just an error.
I tried to cargo build the remaining code but there were errors, maybe it failed to apply a rustc suggestion
