--- Comment #10 from Richard Guenther <rguenth at gcc dot gnu.org> 2010-11-11 14:05:29 UTC --- Ah, I think it has gone latent by disabling frame-pointer by default on i?86-linux and enabling (async) unwind tables. No unwind tables was exactly the problem, on i?86-linux at least. So on i?86-linux the issue only reproduces with -fno-omit-frame-pointer -fno-asynchronous-unwind-tables -flto-partition=1to1. I have a hack.
