// Test that an unboxed closure that mutates a free variable will
// cause borrow conflicts.


fn main() {
    let mut x = 0;
    let f = || x += 1;
    let _y = x; //~ ERROR cannot use `x` because it was mutably borrowed
    f;
}

Removed `ignore-test-compare-mode-nll` from unboxed-closures tests by strengthening the tests (by adding no-op references to the closures doing the borrows after the conflicting borrows, thus forcing the lifetimes to resemble lexical scopes even under NLL). 2018-08-15 23:39:30 +02:00
