Unity Vumark crash on IOS, happens occasionally on datasetLoader

February 24, 2017 - 2:46am #1

Hello,

we get crashes on Vumark dataset loading with attached Vumark dataset zip. Also attached is our DatasetLoaderMinimal class (as text) that does reproduce the crash. The other setup is Unity 5.3.7f1 (same crash comes with 5.5) and Vuforia 6.2. Xcode is 8.2.1 and crash happens on various IOS versions, both on pads and phones. Works on android and loads dataset with image targets without any problems.

Tricky part is that crash happens occasionally, around every 5th time app runs, always on same call in Vuforia (see screenshot).

Best,

Juha

Hi,

sorry for delay. We were able to pinpoint the crash to the Vumark dataset in question. We made another vumark from same .AI file and it does not crash.

Thanks for investigation!

Hello,

We were unable to reproduce this issue.

Note that due to the provided script downloading the dataset from an external server, we were unable to exactly replicate your scenario. Rather, we instead attempted to load your dataset multiple times from the local file system but no crash.

Have you attempted something similar? Perhaps this could help isolate the issue to something related to the downloading and unzipping steps?

Thanks.
