(see http://bugs.python.org/issue16991)
I an working on resolving an intermittent segfault that my C OrderedDict patch introduces. The failure happens in test_configparser (RawConfigParser uses OrderedDict internally), but only sporadically. However, Ned pointed out to me that it appears to be related to hash randomization, which I have verified. I'm looking into it. In the meantime, here's a specific question. What would lead to the pattern of failures I'm seeing? I've verified that the segfault happens consistently for certain hash randomization seeds and never for the rest. I don't immediately recognize the pattern but expect that it would shed some light on where the problem lies. I ran the following command with the OrderedDict patch applied: for i in `seq 1 100`; do echo $i; PYTHONHASHSEED=$i ./python -m test.regrtest -m test_basic test_configparser ; done Through 100 I get segfaults with seeds of 7, 15, 35, 37, 39, 40, 42, 47, 50, 66, 67, 85, 87, 88, and 92. I expect the distribution across all seeds is uniform, but I haven't verified that.
