The attached csd segfaults when started with csoundSession. It runs 
normally when started from csound in the command prompt or with QtCsound.

Simple program to test:

from csoundSession import CsoundSession

cs = 
CsoundSession("/Users/richard/PycharmProjects/OscCtcSound/csds/temp.csd") 
;<== it crashes here
cs.start()

Apparently it has to do with the py* opcodes. When I comment these out, the
csd does not crash...

It also crashes with a very simple csd, with the py* opcodes.
Are these supported with ctcsound?

It could be that ctcsound is linked to a different python lib to the one your interpreter is
using and then when they get loaded, they fail. Check that you are running the same libs.
On MacOS, you can use otool -L to see which library is being used (passing the relevant
file to it).

I was thinking about that too.
I think the py opcodes use Python 2.x, don't they? I run my code from 
Python 3.6
But when I run it from Python 2.7 I get the following:

/usr/bin/python /Users/richard/PycharmProjects/OscCtcSound/test.py
Traceback (most recent call last):
   File "/Users/richard/PycharmProjects/OscCtcSound/test.py", line 1, in 

     from csoundSession import CsoundSession

line 24, in 
     import ctcsound
   File "/Library/Python/2.7/site-packages/ctcsound.py", line 33, in 

     libcsound = CDLL("CsoundLib64.framework/CsoundLib64")
   File
