Segmentation fault while opening files with cfgrib

I am not able to open grib file with cfgrib . I am running into a segmentation fault.

I have tested both:

xarray.open_dataset('test.grib2', engine='cfgrib')
cfgrib.open_datasets('test.grib2')

test.zip

When I am using pygrib, all works fine. So I assume a problem with cfgrib.

Versions:

In [10]: cfgrib.__version__
Out[10]: '0.9.10.2'

In [11]: xarray.__version__
Out[11]: '2022.9.0'

In [12]: #xarray.__version__

In [13]: import eccodes

In [14]: eccodes.__version__
Out[14]: '2.27.0'

Dear Daniel,

does using python:3.9-slim-bullseye make any difference? It will give you a more recent version of Python 3.9, and a newer OS baseline image (Debian 11 Bullseye instead of Debian 10 Buster).

With kind regards, Andreas.

Interesting. For me, cfgrib 0.9.10.2 works fine with the data. My only difference from you is that my test environment has eccodes 2.26.0 rather than 2.27.0, otherwise the versions are the same as your original failing one.
