Rustc 활용법 다양한 옵션을 할 수 있다. ㅎㅎ

cargo new foo
cd foo
rustc  -Clto  -Cembed-bitcode=yes -Zvirtual-function-elimination src/main.rs 
./main # this works
> Hello, world!
rustc  -Clto  -Cembed-bitcode=yes -Zvirtual-function-elimination src/main.rs -Copt-level=1
./main
> [1]    2203089 segmentation fault (core dumped)  ./main
