App crashes while testing on XCode Simulator and Real Devices

[cochleas.devel]

Dear all,

I am developing an iOS app for iPhone only at the moment. I have a serious problem.
Any help would be really appreciated.

I build the xcodeproject from qt and open it in xcode. Then I run the simulator.
For iPhone 4 and 4s the app works perfectly (also on real devices with iOS 7.1.2).

For iPhone 5, 5s, 6, 6+ the app crashes during launch and maybe you need
to reopen 3 or 4 times, until it is finally launched ( on real devices with iOS 8.0.1).
When testing with xcode simulator, the process stops at the attached screen (see picture).

@Thread 1: EXC_BAD_ACCESS (code=2, address=0x0)@

The full log message is at the end of the message.
Any idea what goes wrong? I have seen this bug:
https://bugreports.qt-project.org/browse/QTBUG-41443?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel
Is this something relative to my problem?

I am using Qt 5.3.2.
Please help this is urgent.

Any help? Anyone?

I think you should try Qt5.4beta. One of the comments in the bug you reference says 'will be fixed in 5.4.' As the release notes for 5.4 discuss, it includes many fixes, including some for iOS8.

I too saw a EXC_BAD_ACCESS on 5.3.2 (not saying its the same as yours) and other issues, and Qt5.4beta seemed to make them go away.

Hi bootchk,

thanks for your reply! I tested with Qt.5.4beta and the crash still occurs. I don't think that they have the issue fixed yet.
