defer on inline function runs indefinitely

[kenny-statsig]

The following program sample.go triggers an unexpected result

package main

import "fmt"

func run(fn func() bool) bool {
	fmt.Println("run")
	for {
		return fn()
	}
}

func main() {
	run(func() bool {
		deferred := func() {
			fmt.Println("deferred")
		}
		defer deferred()
		fmt.Println("done fn")
		return true
	})

	fmt.Println("done main")
}

Expected result

run
done fn
deferred
done main

Got

Nothing, Eval runs indefinitely

Additional Notes

Seems to only happen when defer is used on a function defined inline/same scope as where defer is called from. For example, the following code works:

package main

import "fmt"

func run(fn func() bool) bool {
	fmt.Println("run")
	for {
		return fn()
	}
}

func deferred() {
	fmt.Println("deferred")
}

func main() {
	run(func() bool {
		defer deferred()
		fmt.Println("done fn")
		return true
	})

	fmt.Println("done main")
}
