commit 12af831615a77e1920de5943bf2251b6c01b0e25
Author: Owen Avery <powerboat9.ga...@gmail.com>
Date:   Tue Sep 3 22:49:15 2024 -0400

    Fix v0-mangle1.rs test when run with ASAN
    
    gcc/rust/ChangeLog:
    
            * util/rust-canonical-path.h
            (CanonicalPath::CanonicalPath): Properly initialize crate_num
            with copy constructor.
    
    gcc/testsuite/ChangeLog:
    
            * rust/compile/v0-mangle1.rs: Make v0-mangle test more crate_num
            agnostic.
