Rust 1.1 internal compiler error: unexpected panic possibly related to E0252

[kykc]

I tried to compile this code with cargo:
https://github.com/kykc/rustlogtest2
I've expected regular compiler error E0252 as my code is indeed invalid
Instead I've got unexpected panic inside rustc

Could not compile `rustlogtest2`.

This has already been reported in #25763 and fixed in #25791

AFAIU this should be fixed on stable in the next release-cycle*

Thanks, seems that I've failed to use search properly 👍

Closing since it was already fixed!
