crash after autocommand call <SID>ClangCompleteInit()

[xinranli1993]

I found that my vim will crash when opening file with .c or .cc appendix. Tracking down the issue to clang_complete, but it might also because of my configuration of python?
Looking forward to your help, thanks!
My clang_complete config:

  1 " path to directory where library can be found
  2  let g:clang_library_path='/usr/lib/llvm-3.8/lib'
  3  " or path directly to the library file
  4  let g:clang_library_path='/usr/lib64/libclang.so.7'

python version 3.7
vim version 8.1.542
clang_complete installed with pack

Debuging message from vim:

From the error output, this doesn't look like clang_complete issue to me.
Does the following throw the same error?
$ python3.7 -c "import codecs"

[danboxall1988]

I know this was a long time ago, but I'm having the same issue. Running
$ python3 -c "import codecs" does not throw an error.
