std::array alignment

Question

Trying out std::tr1::array on a mac i\'m getting 16 byte alignment.

sizeof(int) = 4;  
sizeof( std::tr1::array< int,3 > ) = 16;  
sizeof         


        

Answer 1

Since posting, turns I get what I want swapping the IDE setting from the default to..

LLVM compiler 3.0 Language:
  LLVM C++ standard library:
    =libc++ (LLVM standard library with c++0x support.)

( CLANG_CXX_LIBRARY = libc++ )l

Previously the setting was "libstdc++ (gcc c++ standard library)" which appears to have the padding, and that allowed me to include instead of ; and now

sizeof(array)==sizeof(T)*N

this is all in Xcode 4.2 on mac osx lion. I'm hoping one is simply deprecated and that this behavior is what i'll get on other platforms?
