This is an unofficial snapshot of the ISO/IEC JTC1 SC22 WG21 Core Issues List revision 112e. See http://www.open-std.org/jtc1/sc22/wg21/ for the official list.
For certain data types on some hardware, a given object can be accessed most efficiently with one alignment but can be successfully accessed if allocated at a less-stringent boundary. Should the Standard specify the minimum or the preferred alignment as the value of the alignof?
Rationale (June, 2014):
The existing wording is clear that the result alignof is the minimal alignment. If an operator returning the preferred alignment is desired, that request should be addressed to EWG.
