Segmentation Fault on Test #17: testMagneticLensPythonInterface

Dear developers,

I ran into a Segmentation Fault while installing CRPropa.

System Information:

Operating system: macOS Monterey 12.4
Laptop
Python version: 3.10.5
Swig version: 4.0.2
Cmake version: 3.20.1

Here is the test failing:

The following tests FAILED:
     17 - testMagneticLensPythonInterface (SEGFAULT)
Errors while running CTest
Output from these tests are in: /Users/angelinapartenheimer/wipac_research/crpropa_update/CRPropa3/build/Testing/Temporary/LastTest.log
Use "--rerun-failed --output-on-failure" to re-run the failed cases verbosely.

The test fails without output, which isn't super helpful. I did view a similar issue on GitHub: https://github.com/CRPropa/CRPropa3/issues/316 As @rafaelab suggested, I made sure that the assertEquals() in the test file were replaced by assertEqual(), and they already were.

I was stubborn and decided to use CRPropa anyway. The issue I run into occurs when I run one of the examples listed on the documentation page: https://crpropa.github.io/CRPropa3/pages/example_notebooks/galactic_lensing/lensing_cr.v4.html

Specifically, I get issues with this block of code:

#stack all maps
crMap = np.zeros(49152)
for pid in M.getParticleIds():
    energies = M.getEnergies(int(pid))
    for i, energy in enumerate(energies):
        crMap += M.getMap(int(pid), energy * crpropa.eV )

When I run this, my Jupyter kernel dies every time. I suspect this is related to the test #17 SegFault, as this exact block of code exists inside the testMagneticLensPythonInterface test file under "test ParticleMapsContainer()".

Any hint as to what could be going wrong would be very helpful. Thank you so much!
