Via reverting the applicable compiler-side\ncode changes, I've re-confirmed that the original problem also applied to\nOpenACC.\n\nFor good measure, also fix up the OpenACC: the array assignment/constructor\nbefore the loop and 'if'/'any' check after the loop execute in gang-redundant\nmode, which -- in presence of multiple gangs executing, as implied by the\nOpenACC 'loop' construct with 'gang' clause -- is dubious, even if probably\nbenign in this specific case here, I suppose.
