// REQUIRES: stable-runtime

// of allocated at line 42 memory thus memory block allocated in Leak() function
// ends up to be classified as reachable despite the fact we zero out 'sink' at
// the last line of main function. The problem doesn't reproduce with ASan because
// quarantine prohibits memory block reuse for different allocations.
