For info, I did a try on a ppc64le VM with a gdb version: gdb-7.7.1-14.fc21 and test_gdb of python-2.7.8-4.1.fc21 build went succesfull. I upgraded this machine with gdb-7.8-19.fc21 and I hit test_gdb kernel is 3.16.0-0.rc6.git1.1.fc21
python3-3.4.1-15.fc21 has been submitted as an update for Fedora 21. https://admin.fedoraproject.org/updates/python3-3.4.1-15.fc21
python3-3.4.1-15.fc21 has been pushed to the Fedora 21 stable repository. If problems still persist, please make note of it in this bug report.
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
This message is a reminder that Fedora 21 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 21. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '21'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 21 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 21 changed to end-of-life (EOL) status on 2015-12-01. Fedora 21 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
The GDB tests are still skipped on some architectures. We will eventually want to find the root cause here.
This bug appears to have been reported against 'rawhide' during the Fedora 28 development cycle. Changing version to '28'.
Marcel, could you try looking into this bug when you get some time?
Python 3 doesn't have this issue anymore. Changing it to python2 (will need to test if it actually reproduces there atm).
Closing this as we can't realistically get enough time to investigate this issue and it's a low priority one as well. Please re-open if the bug still affects you and we'll try to raise the priority.
