John, thanks for reporting the PR and working on it.
I guess that the last patch (for pr48380) I sent should solve the problem too.
Unfortunately, I did not get an approval for the patch yet.
I'd recommend you to check the patch first because it might save you a lot of
time because the problem occurs in reload and it is hard to analyze the reload.
But the real reason of the problem is in wrong IRA directions.
