Issue Description:

We found memory leak with DispatchWorkItem on android-armv7
After a quick research, this leak doesn't reproduce on linux x86_64 and android arm64
So looks like it affects all 32bit platforms
Here is a sample:

import Dispatch

let group = DispatchGroup()
let queue =

class A {
    deinit {

func test() {
    let a = A()
    queue.async(group: group, execute: DispatchWorkItem {


deinit not called
And without DispatchWorkItem this code also works fine
