Array constructor is not thread safe

If you assign an array using an array constructor such as [1.2, 3.0, 4.0] or the older (/1.2, 3.0, 4.0/) then it assigns random number occasionally when run under openMP. My support number is 551578.

Attached example. Please run in debug mode.

No error occures in release mode which makes me think that some temporary memory is used in debug mode that gets optimised out in release mode.
