dateutil 2.6 gives segfault in normalizing timestamp with datetutil timezone · Issue #14621 · pandas-dev/pandas (original) (raw)

Newly release dateutil 2.6.0 breaks some of the tests related to the use of dateutil timezones (travis is therefore currently failing)

Original report:

A small, complete example of the issue

I maintain central installs of miniconda environments that include pandas. My previous environment with pandas 0.19.0, if I did this

python -c "import pandas; pandas.test('fast')"

it worked. Now with pandas 0.19.1, it seg faults. Other packages may have been updated in the new environment.

Below are details - first the failure in my ana-1.0.5 environment, it is clearly segfaulting on a test maybe 2/3 the way through? Then the success in my ana-1.0.4 environment, then the pd.get_versions() in the working old environment, and finally in the newer environment where it fails:
