Description Jan Staněk 2018-04-26 09:38:16 UTC

Description of problem:
When rebuilding the package for CentOS, the test suite crashes due to segmentation fault in infinite recursion test.

Version-Release number of selected component (if applicable):
rh-python36-python-3.6.3-3.el6

How reproducible:
Rebuild the source package in CBS, in target sclo6-rh-python36-rh-el6

Actual results:
The build fails due to test suite crash.

Expected results:
The build passes.

Additional info:
- The failed build with logs: https://cbs.centos.org/koji/taskinfo?taskID=399798
- The issue seems to not manifest on RHEL.
- Rebuild of previous release (rh-python36-python-3.6.3-1.el6, https://cbs.centos.org/koji/buildinfo?buildID=20502) was completed successfully.

Seems related to https://bugs.python.org/issue27277

Will try to do some tests with increasing the stack size.

Comment 3 Charalampos Stratakis 2018-04-26 10:57:45 UTC

Tried in mock but the issue does not reproduce there, and I don't have any experience with the CentOS build system. Could you refer me to some guidelines on how to do a scratch build there?

Also check this as well: bug 1292462

CBS guide: https://wiki.centos.org/HowTos/CommunityBuildSystem

However, this requires joining a SIG. Although I would certainly be grateful if you joined us, let me try it first with the `ulimit` workaround :)

Relevant line from the python3 fedora SPEC [0] (obviously we don't need it only for ppc here).

Comment 6 Jan Staněk 2018-04-26 12:46:04 UTC

The `ulimit` workaround seems to work: https://cbs.centos.org/koji/taskinfo?taskID=400793

Comment 7 Petr Viktorin (pviktori) 2018-06-07 14:46:29 UTC

Can this issue be closed?

Comment 8 Jan Staněk 2018-06-12 12:21:26 UTC

The package was successfully built and passed testing, so it seems to work. The issue can be closed.
