Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |MOVED Status|UNCONFIRMED |RESOLVED --- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- This is not a GCC issue as __register_frame_table is declared as extern. This is almost definitely a glibc issue really. But I doubt glibc can be compiled at -O0 because of these issues.
