No, at least not for what concerns correctness of the results. With the new versions of libxc that test is regularly taking 35 iterations to converge instead of the 25 in the benchmark, but converges to the same ground state as in the benchmark. Pietro

The only one that failed had the following console output. pw_metaGGA - metaGGA-spin.in: **FAILED**. n1 ERROR: absolute error 1.00e+01 greater than 8.00e+00. (Test: 25.0. Benchmark: 35.0.) Is this cause for any concern? and if so is there any further diagnostics to pinpoint the root cause?
