On my system, makeotfexe_test.py enters into, what appears to be, an infinite loop in test_duplicate_single_sub test. This seems to be caused by nFeatures variable in fillFeatureList() getting a random huge value when there are no features in the file, as spanLimit can be 0 and the code ends up trying to access t->subtable.array[-1].index.feature.
