Thanks for the fix. What's the status on backporting this to 8 and/or 7?

--- Comment #4 from roland at gnu dot org ---
That fix (applied to trunk) works for my test case and for the original
real-world case I reduced it from.
Will it be backported to 7 and 8?
Thanks for the quick work as usual, Jakub!

r190487 is the breaking change. I tested reverting that (relative to 4.8
branch) and it solved the problem.
Note I'm more concerned with having this fixed on the 4.8
