%Eigen does explicit vectorization, and while that is appreciated by many users, that also leads to some issues in special situations where data alignment is compromised. %Eigen does explicit vectorization, and while that is appreciated by many users, that also leads to some issues in special situations where data alignment is compromised.
Indeed, since C++17, C++ does not have quite good enough support for explicit data alignment. Indeed, prior to C++17, C++ does not have quite good enough support for explicit data alignment.
In that case your program hits an assertion failure (that is, a "controlled crash") with a message that tells you to consult this page: In that case your program hits an assertion failure (that is, a "controlled crash") with a message that tells you to consult this page:
