        let symbol_address = frame.symbol_address();

        // Resolve this instruction pointer to a symbol name
        backtrace::resolve(ip, &mut |symbol| {
            if let Some(name) = symbol.name() {
                // ...
            }
            if let Some(filename) = symbol.filename() {
                // ...
            }
        });

        true // keep going to the next frame
