Description Tim Waugh 2014-09-02 13:45:37 UTC
Description of problem:
When attempting to diagnose bug #1133860, I ended up with:

Process record does not support instruction 0xc5 at address 0x3ba174add0.

Version-Release number of selected component (if applicable):
gdb-7.8-20.fc21.x86_64
gcc-4.9.1-7.fc21.x86_64
control-center-3.13.90-1.fc21.x86_64

How reproducible:
100%

Steps to Reproduce:
1.debuginfo-install control-center
2.G_DEBUG=fatal_warnings gdb --args gnome-control-center online-accounts
3.tbreak main
4.run
5.record
6.continue

Actual results:
Continuing.
Process record does not support instruction 0xc5 at address 0x3ba174add0.
(null)Process record: failed to record execution log.

I don't see this error on Fedora 20.

Comment 2 Fedora End Of Life 2015-11-04 15:11:57 UTC
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bug reports from releases that are no longer maintained.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.
