Most often such segfaults are due to c-extension modules, and should 
print some type of RPython debug exception to stderr. Do you have access 
to the stdout/stderr of the process? Is there any more information? We 
no longer support that version. The last version of python3.6 was 
v7.3.3, maybe updating to that would help. If you can update further 
that might also help.
