Crossplatform compatibility error

[macosinternals]

Take simple source:

fn main() {
io::println("Hellow world")
}

Compile it on Mac OS X 10.8 and run on Mac OS X 10.7.

Result:

Illegal instruction: 4

Same issue with Rust compiler. If it was built on 10.8 it'll crash on 10.7 with same message.

2 things: 1) Does this still happen? and if it does, 2) is this an actual issue? I mean unless you deliberately cross-compile it, this doesn't seem too strange to me.

[catamorphism]

Not a bug; executables don't normally do anything sensible on a different target than the one they were compiled for.

[astavonin]

Are you kidding? All OSX application can be compiled on one version of OS and be running on other one.
