[Bug libstdc++/13121] Inserting struct with valarray in map fails

[bangerth at dealii dot org]

The reason why the standard says this is undefined behavior is that
the creators of valarray wanted to have maximum speed for this class.

A check for the length and possibly throwing an exception might sacrifice
this goal, although it would of course be much cheaper than the actual
memory allocation this "feature" is to prevent. I leave this up to
the libstdc++ maintainers -- maybe their new debug mode lib has this
fixed already.
