Error with leading digit in '1' in src/trans/mangling_v2.cpp:85

[iamanonymouscs]

When attempting to compile the code with mrustc:

Code

$ cat 1.rs

#![crate_type = "lib"]
pub fn get_u16_from_unaligned_manual(data: [u8; 1]) -> u8 {
    data[0] << 16
}

Command

mrustc -L output-1.54.0 1.rs
It seems there is an Internal Compiler Error (ICE) occurs, with the error message:

The root cause is the crate name being "1" (as the input file is 1.rs - I can only tell that from the stray - main: params.outfile = lib1.rlib line.
