Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- See Also| |https://gcc.gnu.org/bugzill | |a/show_bug.cgi?id=42364 --- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> --- This works though: typedef struct __attribute__((aligned)) {} a ; My bet is this started to ICE when attribute support was added to templates.
