The reason turns out to have nothing to do with PODs. Rather, it is due to the fact that on Cygwin, BIGGEST_FIELD_ALIGNMENT is set to 8 bytes. So, even though the __m128 type has 16-byte alignment, Base 2 has only 8 byte alignment, which results in a size of 24 bytes. -- What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution| |INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16381
