--- Comment #12 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Paul Eggert from comment #10) > This GCC bug caused Emacs to crash in mysterious ways; see > <https://bugs.gnu.org/78473>. > > We worked around the bug by changing Emacs 'configure' and 'make' to always > use gcc -fno-tree-rsa when that option is supported; see > <https://github.com/emacs-mirror/emacs/commit/ > 9dfc605654bea7a1346da224cf7e1eec850e05c4>. > > It'd be nice if GCC worked out of the box. Perhaps -fno-tree-rsa should be > the default until this GCC bug is fixed? Also it is not obvious from the Emacs bug report it is exactly this bug. It could be another bug that is exposed by SRA
