Attempting to build custom image results in Seg Fault

Currently using Julia 1.3.1 and installed pyjulia via `python3 -m pip install --user julia`

Per instructions from this [link](https://pyjulia.readthedocs.io/en/latest/sysimage.html), I am trying to run `python3 -m julia.sysimage sys.so` to obtain a custom julia image. The motivation behind this is to work around the "Python interpreter is statically linked to libpython" issue explained [here](https://pyjulia.readthedocs.io/en/latest/troubleshooting.html). However, I keep getting the following error involving a seg fault (or some variation of, which involves consuming a ton of memory):


I searched throughout the web and github issues, but could not find a solution. Thanks in advance!
