Segmentation fault when loading grib #2938

Description

@malininae

When working on #2892, I installed the most recent version of the core from source and created an environment from enviroment.yml. However, when loading the grib file into a cube, I ended with Segmentation fault (core dumped) on load

So my error hunt and comparison to a released v2.13, which worked, brought me to realization that issue is with the environment, and namely with packages eccodes and python-eccodes. If I install the environment from here, I end up with following environment:

While a working environment had (couldn't paste full)

eccodes      2.41.0    h8bb6dbc_0    conda-forge
python-eccodes      2.37.0 py313h29aa505_1      conda-forge
python     3.13.9        hc97d973_101_cp313      conda-forge

When I downgraded in the segfault environment eccodes and python-eccodes from 2.44.0 in both to 2.41.0 and 2.37.0 and all works now.

Just wanted to flag it for @valeriupredoi since he often works on the environments.
