commit 3493f4d27c705fa1baa0544ad51f36dd7b6779ac
Author: Alexandre Oliva <oliva@adacore.com>
Date:   Wed Feb 23 05:00:07 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.
