make_shared causes stack overflow with large objects

Description

Hello,

if #4256 really fixed the problem, then this is a regression. I encountered the bug with Boost 1.42, 1.44, 1.50, and 1.52.

In my project I have relatively small stack sizes due to a large amount of threads I have to support. Creating objects via boost::make_shared crashes due to large object size. I've attached a test case that shows the problem in MacOSX. If I enable C++11 support and use the smart pointers from std instead of the boost one, everything works fine.

Thanks, Gregor
