--- Comment #1 from Martin Reinecke <mar...@mpa-garching.mpg.de> --- Problem seems to be related to the use of __restrict__. If I remove the DUCC0_RESTRICT from the function definitions of "radb3", "radb4" etc., the problem goes away. However I don't see where I'm violating the promise made by __restrict__ in these functions ...
