// Despite the absence of any unsafe Rust code, foo.rs in this test would,
|
|
// because of the raw function pointer,
|
|
// cause undefined behavior and fail to print the expected result, "4" -
|
|
// only when activating optimizations (opt-level 2). This test checks
|
|
// that this bug does not make a resurgence.
|
|
// Note that the bug cannot be observed in an assert_eq!, only in the stdout.
|
|
// See https://github.com/rust-lang/rust/issues/20626
