Actually it looks like the regression was introduced in 10.3. It works in 10.2
and earlier.

Hi Martin,
This is fixed in 12-branch onwards.
I have not been able to find the fix - could you find it, please? I tried
comparing the diff in comment #2 with the current head but the differences in
the affected code didn't do the job.
Cheers
Paul

Many thanks, Martin.
I'll try to apply it to 11-branch, if for no other reason than to see if it
does so cleanly. Tobias must have thought that it was too invasive to backport.
So I can keep track, September 2021:

PS How do you do this location - by hand or do you have a script to do the
bisection?

I have a script that uses pre-built GCC binaries:

I think that we should take this view, given the imminent opening of 15-branch.
