Package: python3-pyopencl-dbg
Version: 2018.1.1-2
Severity: important


hello, I was struggling on an autopkgtest failure forone of my packages (pymca)
At the end I findout that the problem comes from pyopencl.
When I try to import pyopencl, I get this.

$ python3.7-dbg -c "import pyopencl"
/usr/lib/python3/dist-packages/pkg_resources/_vendor/pyparsing.py:943: 
DeprecationWarning: Using or importing the ABCs from 'collections' instead of 
from 'collections.abc' is deprecated, and in 3.8 it will stop working
  collections.MutableMapping.register(ParseResults)

  elif isinstance( exprs, collections.Iterable ):

* op->_ob_prev->_ob_next

but it works with python3.7

$python3.7 -c "import pyopencl"


no segfault.

thanks for considering

Sorry, took me a while to get into this.

I'm interested to hear about any API/ABI breakage in cffi modules, but I
just can't find the culprits, here.

python3-pyopencl-dbg version 2018.1.1-2 didn't contain a python 3.7
module.

The other clone of this bug seems to show that the wrong builds of the
library were being used, for some reason.

There isn't a cffi bug that I can reproduce here.

I used:
deb [check-valid-until=no] 
https://snapshot.debian.org/archive/debian/20180922T000000Z/ unstable main

# dpkg -L python3-pyopencl-dbg
