Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Keywords| |build --- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> --- That type has these members: unsigned char _M_canary; unsigned char _M_size; unsigned char _M_align; unsigned char _M_next[sizeof(_Chunk*)]; So it should have the same alignment as an unsigned char, no?
