[morganchen12]

Looks like a memory error in nanopb. It'll be difficult to debug this without repro steps or a sample project. Can you share your project or any additional details?

cc @baolocdo

[baolocdo]

What is the version of Firebase SDKs? Can you provide the Podfile? Thanks

[ryanwilson]

@liuzhen2008 any update on this?

[morganchen12]

closing, please re-open if this is still an issue.

[liuzhen2008]

For posterity sake,

I did a clean and updated my firebase to 4.3.0

Everything seems to work fine.

Sorry for the distraction guys.

[ryanwilson]

@liuzhen2008 no worries, thanks for using Firebase and please file an issue if you run into any problems! :)

[Saurman]

Hello, I am still getting this issue. Obj-c project, using only Firebase analytics (pod Firebase/Core). App works fine in Debug mode but instantly crashes on [FIRApp configure] if archived (Release) and installed

[paulb777]

@Saurman It may be that you're running into #1052 that others have reported occurs in Xcode 9.3 but not 9.2.

[coolgastjen]

Still having this issue and using 4.12.0

I did notice that changing the bundlename to another name resolves the crash. That is also the reasen why new apps work fine when created in 9.3, but apps created before 9.3 crash at FIRApp configure.
Both app run exactly the same code.

However. This is not an option because we do not want to release the app as a new app.

We rolled back to xcode 9.2 and this seems to be the only working solution for now.

[Saurman]

thats not an option for me

[georgbachmann]

I am also having this issue today. Also it seems as if it's gone when I don't have the debugger attached...
Just did a pod update

Installing Firebase 4.13.0 (was 4.12.0)
Installing FirebaseAnalytics 4.2.0 (was 4.1.0)
Installing FirebaseCore 4.0.20 (was 4.0.19)

but am still having the issue.

[georgbachmann]

Managed to get a crash-log be surrounding the call with a try-catch:

[paulb777]

Thanks for the backtrace @georgbachmann. Seems to be a different problem than was originally reported here, so I'll reopen and recategorize it.

[chliangGoogle]

I haven't been able to reproduce the case but for your log specifically, can you check whether your language setting is nothing irregular? Specifically can you print out the following info to see if it's nil?
[[NSLocale preferredLanguages] firstObject]

Next release we will add better checking to avoid case like this.

[georgbachmann]

Ok, so for me in my Simulator it's @"de-US",... so not nil...
Other fun-fact... It's not crashing any more today without ANY change since yesterday?!?

[morganchen12]

We've fixed this internally and it'll be out in an upcoming minor release.

If you're still running into this issue, please comment and I'll reopen it.
