Confirmed. The first patch there.
I will still prepare a patch with the testcase to avoid an independent
regression.

commit r12-7383-g33c7df5854ecb31e2d645ab672ad3987b591ebfd
Author: Alexandre Oliva <oliva@adacore.com>
Date: Thu Feb 24 22:03:38 2022 -0300
Add testcase from PR103845
This problem was already fixed as part of PR104263: the abnormal edge
that remained from before inlining didn't make sense after inlining.
So this patch adds only the testcase.
