Hi Stephan - You're welcome; glad you found a work-around that fixes the issue!
I'll let others speak to whether Volk is thread-safe.
I can say that the scheduler is the same no matter the OS; but, the actual
thread scheduling can be worlds different on different OSs. Thus, executing on
Linux might be stable at the same time as on OSX and Window would not be; it
can happen.
Good luck with your GR work! - MLD
