Joseph Huber 6dd791bca8 [OpenMP] Check output of malloc in the device for debug
A common problem is the device running out of global heap memory and
crashing due to a nullptr dereference when using the data sharing stack.
This explicitly checks that a nullptr was not returned by malloc when
debugging field 1 is enabled.
