Alignment issues

Detailed Description

Modules
	Explanation of the assertion on unaligned arrays
	Hello! You are seeing this webpage because your program terminated on an assertion failure like this one:
	Fixed-size vectorizable Eigen objects
	The goal of this page is to explain what we mean by "fixed-size vectorizable".
	Structures Having Eigen Members
	Using STL Containers with Eigen
	Passing Eigen objects by value to functions
	Passing objects by value is almost always a very bad idea in C++, as this means useless copies, and one should pass them by reference instead.
	Compiler making a wrong assumption on stack alignment
