3.6 is ancient. There isn't anything we could do about your crash even if we
found the cause (also, 3.6 had plenty of other issues as well).

I'd recommend trying a newer version of the debugger, 3.8 at the very least.

OK, it turns out there is a version of libsosplugin.so that works with later
LLDB versions. I still get a Segmentation fault in 5.0 (but not 3.9 or 4.0):

$ lldb-5.0
(lldb) script
Python Interactive Interpreter. To exit, type 'quit()', 'exit()' or Ctrl-D.
>>> lldb
>>> Segmentation fault (core dumped)

Sometimes it works the first time, but crashes the second time:

(lldb) script
Python Interactive Interpreter. To exit, type 'quit()', 'exit()' or Ctrl-D.
>>> lldb
>>> <module 'lldb' from '/usr/lib/python2.7/dist-packages/lldb/__init__.py'>

>>> lldb
Segmentation fault (core dumped)
