--- Comment #2 from Jeffrey A. Law <law at gcc dot gnu.org> --- It's not in gcc-15 as far as I know. I would much rather sit down and understand the failure rather than revert, even if it was in gcc-15. The original code was plain wrong and the failure below strongly suggests we're calling free on a ggc allocated node which is clearly wrong as well.
