Hey,
We’re building our app with Unity 5.5.0f3 and getting a SIGSEGV crash on startup. The crash happens when booting up the app once or twice, and then it correctly boots up. I have absolutely no clue what’s the cause of this. I’ve tried making release builds. Debug builds. FAT and arm only builds. Tried building with il2cpp but that didn’t make it onto the device because of errors.
Does anyone have any ideas?
Cheers,
Paul

Hard to tell from just this output, but it appears that you may have a plugin/library that is trying to initialize the GPS? Maybe the GPS library does not initialize immediately, so you might want to check when you try to access its functionality.
After having done some research it seems like Google VR being built with Unity 5.5 that is causing the crash. Several people on the GVR forums have the same problem.
FYI: I do not use Google VR and I have the same issue since upgrading to Unity 5.5

@Rainking , do you use location services in the project? There is a fix for a similar crash in the 5.5.1p3(EDIT:5.5.1p4, sorry for mistake!), please let me know how it works, especially if it crashes 
tagging @pgeorges-dpt as well
Got the same crash in my project.
The 5.5.1p3 did not fixed this (And I do not see the related fix in the change log).
It does not crash anymore when disabling the Location service,
Which seems to indicate that this is the right problem, but is the fix really present in the 5.5.1p3 ?
@Jonas_Sid do you have a link to this issue ?
@WillFvrther , sorry it seems I made a mistake. It’s gonna be in 5.5.1p4.
@Jonas_Sid , yes I used location services and found out a bit later that this was the root cause. Currently, I do not use this code part. I’ll try the patch soon, thank you! When will be p4 released?
