I wrote a not so big rust projet.
It was compiled (and then works) fine in debug mode but the compilation in release mode (opt.level=3) is never finishing.
If I use opt.level=2, it is fine (compilation and exectable).
Only level 3 is suspected to fall in an infinite (or very long) loop.
Of course, I could give my rs files but I don't know where I can report this bug.
