Hi
so  1.9.20 got released

I noticed this about <https://kotlinlang.org/docs/whatsnew1920.html#custom-memory-allocator-enabled-by-default|memory allocator> ,
How can i enable it for kotlin 1.9.10 ? (i don't want to migrate to 1.9.20 as of now)

<https://kotlinlang.org/docs/whatsnew19.html#preview-of-custom-memory-allocator>
`-Xallocator=custom`
```kotlin {
    macosX64("native") {
        binaries.executable()

        compilations.configureEach {
            compilerOptions.configure {
                freeCompilerArgs.add("-Xallocator=custom")
            }
        }
    }
}```

Thanks ! <@U8LKPHCCW> , i applied it like this

```listOf(
        iosX64(),
        iosArm64(),
        iosSimulatorArm64()
    ).forEach {
        it.compilations.configureEach {
            compilerOptions.configure {
                freeCompilerArgs.add("-Xallocator=custom")
            }
        }
    }```
This resolved over 200+ memory leaks ! , the ios team were scolding me over them :face_holding_back_tears:
