Yes, I discovered this flaw while working on PR 80969 but I hadn't found
an actual testcase where it caused a problem yet. I'm about to submit
my patchset for review, so sorry I didn't get it committed sooner. My
patch set further improves sp_valid_at and fp_valid_at since it's
possible that the the last offset the frame pointer can be used to
access is not equal to realignment offset. I'll try to get this out
tonight or tomorrow.
Thanks!
Daniel
