My notes suggest it might be -ffold-mem-offsets which is a new pass in GCC 14. We had a few problems with it on HPPA. I thought they were all fixed...

Thanks, I'll poke more. Just upgrading the machine first.

Emailed Dave & Helge for some help. I'm looking in the Emacs source but I don't see anywhere they would rely on this...
Dave has fixed this in GCC. It'll be in the next 14/15 snapshots.
