I take that back. My notes indicate I looked into this failure on March 15th. The patch you referenced was dated Feb 10, so I assumed it was already in when I looked into it: my confirmation amounted to checking what I had observed according to my notes, and when. But now that you asked me to investigate it again, I used a far more recent tree, and I failed to duplicate it. Digging further, I found out the patch, despite its commit date, was only merged into gcc-12 on March 16th. What I was missing to get the intended effects of the fix was just a fresher tree athat actually contained the fix. I suppose this means we don't need the testsuite tweak, after all.
