> I pushed a proposed change to the scratch/bug64391 branch.
> 
> It contains three commits:
> 
> - b741dc7fcd which is the minimal possible commit to fix this bug
> 
> - 01fb898420 which moves a few statements from the callee 
> (internal--label-restriction) to its only caller 
> (internal--labeled-narrow-to-region), and simplifies the code accordingly
> 
> - c52ade305e which is optional, and makes the symmetrical change for the 
> widening case

OK, please merge the first two commits to the release branch, and
thanks.
