I looked into the working draft of Fortran 2015 (J3/16-007r1). In Note 12.52 it
says:
The above constraints are designed to guarantee that a pure procedure is free
from side effects (modifications of dat

How does this work with OpenMP and compiler/FE generated temporary arrays?
If I just do
!$OMP parallel do
