Does this still work if the application is complied in release mode or with optimizations?

Even if not, this is still very useful for debugging

It only works if DWARF is generated. By default, the `release` profile of Cargo sets `debug = false` [0]. But, it's quite easy to override this setting, and have a build that is both optimized and includes debuginfo.
