Comment (by bradleyCPA):

 Is /opt/local/lib/libgcc/libgcc_s.1.dylib really being used on your system
 when testing? Ktrace on mine shows that the
 /opt/local/lib/libgcc/libgcc_s.1.dylib library fails to load in mmap as
 shown way up above. If the needed symbols are resolving elsewhere then
 that failure won't be fatal. You asked about different python versions,
 2.7 and 3.8 also fail similarly:
