[ICE]: Encountered anon const with inference variable args but no error reported

[vinay10949]

Code

I encountered an internal compiler error (ICE) while compiling a Rust project using rustc version 1.84.0-nightly (03ee48451 2024-11-18) on the aarch64-apple-darwin platform. The error message indicates that an anonymous constant with inference variable arguments was encountered, but no error was reported. This appears to be an issue within the compiler.

Anything else?

No response

[BoxyUwU]

are you using any unstable features, do you have a link to the ICEing code or something that would be useful in debugging this?

[vinay10949]

@BoxyUwU I am using this #![feature(generic_const_exprs)]

[jieyouxu]

Looks like #133243 has a reproducer but not minimal. (That report didn't incl. dep version info, asking)
