4 years ago The crash is at https://github.com/rust-lang/rust/blob/b52522ade1f6979a35b24087dadcf5ba5c981cbe/src/librustc_codegen_llvm/back/archive.rs#L274
Noticed that riscv32imac-unknown-none-elf.a contains the file riscv32imac-unknown-none-elf.o twice:
$ ar t /tmp/riscv32imac-unknown-none-elf.a
/
//
riscv32imac-unknown-none-elf.o
riscv32imac-unknown-none-elf.oIt is possible that LLVM couldn't handle this and returned a path without filename or a non-utf8 path.

Code
I don't know exactly where, but somewhere in my embedded Rust code resulted in compile error. The compiler is stable Rust 1.45.0.
I cannot reproduce if I take a part of the source code, maybe I need further help to get a minimum ICE example.
Here's the file:
