Segmentation fault for client library "python-keystoneclient" on Linux Alpine (docker and vagrant image)

[Sofiane Imadali]

Hello everyone,

I am currently experiencing a repeated bug with the python-keystoneclient module specifically on *Alpine linux*. Having already tried keystoneclient on debian, ubuntu and other red Hat based flavors, I never had these problems before.

In order to reproduce the bug, follow the steps:
1- Get an alpine linux either on Docker or Vagrant. Please find the detailed steps here: https://bugs.alpinelinux.org/issues/5038
2- On your python shell, after installing the needed dependencies, do something as simple as: "from keystoneclient import client", "from keystoneclient.v2_0 import client", or "from keystoneclient.v3 import client". All three of these tests should result in a segmentation fault.
3- You can get some limited additional info from gdb.

Thanks to anyone who would help.

- Update: Confirmed and reproducible, here is a complete description and first memory core dump https://bugs.alpinelinux.org/issues/5038. Thanks to Natanael Copa, here is an additional longer backtrace from gdb:

Looks like this was already resolved in the bugreport you mentioned.

I am closing this as "invalid" because it's unlikely we can do anything about it and it was already fixed on the distro side.
