Thanks for testing, it helped me detect a local issue, related to http://savannah.gnu.org/bugs/?53942. This report can be closed.

Also works for me,  I tested multiple times with


N = 1e2;

bm = zeros (N, 1);
for i = 1:N
  bm(i) = test ("griddata3");
endfor


and all 100 tests passed.

This is with hg id 37dbf79c2297 from today.

Maybe the local Qhull library has issues?
