Backtrace of Options Dialog (deleted)

Description Andrew Mulbrook 2016-07-19 16:24:45 UTC
The Qt 5.6.1 update appears to have broken Qt-Creator. After updating, any attempt to open/create a project results in a segfault. Attempting to open the "Tools->Options" dialog also results in a segfault.

All segfaults appear to be due to null ptr deref. 

Version-Release number of selected component (if applicable):

How reproducible:
Reproduces always on current configuration.

Steps to Reproduce:
1. Launch Qt-Creator
2. Use main menu to open Options Dialog (Tools->Options)

Additional info:
Configured system is CentOS 7 w/ all updates. Nothing special.

Attempted to delete ~/.config/QtProject and friends no change.

Run with clear environment, no change.

Run with only Core plugin enabled, no change.

Backtrace of Options Dialog

I get a similar backtrace when attempting to open/create a new project.

Appears to be another user with a same issue on reddit. Did not see that they submitted a bug report however:

Comment 3 David Summers 2016-09-07 20:49:31 UTC
This update has completely broken several people's work-flows at the company we work for.

I've found some of the RPMs to downgrade to:

but not the qt5-qtbase-common-5.6.0-13.el7 RPMs (yet).

Can someone knowledgeable look at this and either give us a reference to all the required downgrade RPMs or fix the issue and provide with normal yum update?

It would be *GREATLY* appreciated, as we use this exclusively in our work.

Thanks in advance.

Comment 4 Rex Dieter 2016-09-08 12:32:38 UTC
It would appear that qt-creator has been stuck at 3.5.x in epel7 due to unsatisfied llvm dependencies of newer versions... however, according to:
the Clang Code Model plugin is optional

I'll look into the possibility of syncing epel7 branch with fedora's master/ branch (containing qt-creator-4.1).  Going on the assumption here that the latest version is better-supported and works better (and fixes this bug).

Comment 5 Rex Dieter 2016-09-08 13:36:16 UTC
Here's a qt-creator-4.1.0 epel7 scratch build for folks to try out:

Sorry, wrong link to scratch build, here's a better (successful) one:

Comment 8 David Summers 2016-09-08 14:42:10 UTC
The qt-creator-4.1.0 epel 7 RPMS seem to have worked!

I can now start qt-creator.

I'll have my team check this out and report back if we find any issues / problems.

Thank you so much!

Hello there,

I have the same problem with qtcreator-3.5.x on CentOS 7. 

However I do not know how to use your build of qtcreator-4 from fedora. 
Could you please indicate how one should use it.

Comment 10 Rex Dieter 2016-10-10 13:30:14 UTC
the qtcreator-4 build was for centos7, except it's been awhile and the scratch build was garbage collected.

I'll re-submit a new build now,

One more bit of positive feedback, and I'll get an official build going.

Other maintainers, any objection(s) to this plan?

Comment 11 George Apostolopoulos 2016-10-18 13:23:02 UTC
Apologies for the late reply.

I tested the qt-creator-4.1.0 and it works also for me on centos7. Opened options dialog, compiled and run a project, everything ok.

Thank you very much Rex.

Comment 12 Rex Dieter 2016-10-18 13:33:40 UTC
Thanks, submitting official build now.
