Unity 5.1.1p2 + Vuforia 4.2 + iOS = EXC_BAD_ACCESS

Hey everyone. I have a project created in unity 5.1.1p2 with vuforia 4.2. when I try to build it for iOS the app crashes in a loop at QCARManagerImpl_UpdateTrackers_m8038 with the error EXC_BAD_ACCESS.

Here is a screenshot of xcode with the issue:

I would like to mention that on Android and Unity Editor everything works perfectly.

Do you guys know what might cause this? Thank you!

I’m not aware of what might cause this error. If you are able to submit this project with a bug report, we can have a look at it here to investigate further.

Hey Josh, thanks for your response. I have removed and re-added vuforia to my project and the error disappeared.

@danieltranca_1

Good, thanks for letting me know!

Hey JoshPeterson, the problem reappeared on iPad 2. On iPad Air(1 and 2) works perfectly. I have attached a sample project in which this issue reproduces. Can you please take a look at it? Thanks!

@danieltranca_1

Can you let me know the bug report number where the project is attached? I don’t immediately see it.

Seems like the upload file doesn’t work but here’s is a link to my dropbox where the project is: https://www.dropbox.com/s/k8bhek62awc4979/Tester.zip?dl=0

Thanks. Can you instead submit a bug report though? That will allow us to run the project through our normal process and provide feedback to you.
