[Patch, Fortran, committed] PR51972 - Extended checking of gfortran.dg/class_48.f90

[Paul Richard Thomas]

Dear Tobias,

I am working on PR52102

> However, as MALLOC_PERTURB_ or valgrind shows, the issue also affects the
> current version. Thus, in the committed patch, only test3() has proper

For some reason, the allocate expression is not being scalarized and
so the 'dest' argument of the elemental _copy is not an array
reference.

Cheers
