Thanks. Now to add to my confusion, on my system __alignof(long double) returns 16, which I presume means that all allocation, static, dynamic and automatic for long double objects are 16 byte aligned.

This is a reasonable choice, that long doubles would be aligned for good performance, unless the alignment is over-ridden by a packed or reduced alignment specification.
