The code as taken from #57702

It is possible the IR is corrupt and fixing #57702 also fixes this.

[KristofferC]

When running it twice, it seems to print... Not sure what is going on with that.

[KristofferC]

Doesn't repro anymore so #57774 probably fixed this as well. Don't think it is worth investigating this further.
