Hi @Blaise,  
When you use a function constructor, you return an object that serves as a rhs in your assignment

```auto
u = LinAlg_Type('u',x)

```

That object is very short lived and will be finalized once the lhs is allocated/assigned.

If you do not want to get this behavior you need to use subroutine constructors with intent out arguments.

You can have a look at this [discussion](https://fortran-lang.discourse.group/t/finalization-ifort-vs-gfortran/7816/11). You will probably find some more details about ‘final’
