It's currently broken due to a silly test that prevents the v0 demangling code from even running. The commit also adds a test, to avoid such problems in the future.

// Valgrind supports demangling Rust symbols (both the "v0" and "legacy"
|
|
// mangling schemes), but we don't want to add a dependency on the Rust
|
|
// compiler for a single test. So this is a C program with function names that
|
|
// are mangled Rust symbols. In the output, they become demangled Rust names.
|
|
// It's a hack, but a useful one.
