Thanks for taking a look. Explicit reallocation is not allowed inside of an OpenMP region but I think allocation is allowed implicitly via intrinsic assignment or privatisation (which works the same as intrinsic assignment).

One of our internal tests failed when I tried to put this in copyHostAssociateVar. I will investigate this and post a followup patch if I get it working.
