Travis failing on segfault at print_versions

[max-sixty]

master is breaking on both the docs and python3.6 print_versions: https://travis-ci.org/pydata/xarray/jobs/479834129

/home/travis/.travis/job_stages: line 104:  3514 Segmentation fault      (core dumped) python xarray/util/print_versions.py
The command "python xarray/util/print_versions.py" failed and exited with 139 during .

Has anyone seen this before? I can't replicate locally, but I likely don't have the same dependencies

This is unfortunate and indeed tricky to diagnose. My guess is there is a spurious bad build somewhere in anaconda land causing this error. Let's wait a day or so to see if things resolve on their own, if now, there are other options for figuring out the offending library.

rasterio might be guilty here. I could replicate the segmentation fault on a linux VM. It worked after uninstalling it. I see on https://conda-forge.org/status/ that rasterio has not been rebuild yet with the new compilers. Since the compiler migration has been completed earlier this week, this might be related.

Does nyone have an idea whether this will be resolved in a couple of days? Otherwise I can try and put a temporary fix in (there's one described in that issue, but I don't have experience with conda so can't assess whether it's likely to be successful)
