Importing FEniCS before TensorFlow causes a crash

I’m working on a library that uses FEniCS and TensorFlow together, and I’m running into an issue where the program crashes if FEniCS is imported before Tensorflow. I can try to avoid the bug by adding some documentation to my library that says that it must be imported before fenics, but it would be nice if the import order didn’t matter.

Based on some googling, I think this is related to exporting symbols with RTLD_GLOBAL. If that is the problem, then TensorFlow says that they have fixed their side of the issue (here https://github.com/tensorflow/tensorflow/issues/13963, https://github.com/tensorflow/tensorflow/issues/13615), but that it might still break if other libraries continue to use RTLD_GLOBAL.

If that’s not the problem, then I can make an issue on TensorFlow’s page, too.

Code to reproduce:

> conda create fenics --name test --no-default-packages -c conda-forge -y -q
> conda activate test
> conda install tensorflow -y -q
> python -c "import tensorflow; import fenics"
> python -c "import fenics; import tensorflow"
