--- Comment #4 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- > My bisection shows r245596 as the start of the regression, r245764 > as well as r245768 fails, not passes. You are right: testing the original code I found the range r245564 (compiles) r245629 (error). Actually I tested r245767 with the variant which compiles.
