Attempting to build custom image results in Seg Fault

[Kchour]

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

Per instructions from this link, 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. 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!
