Crash in com.google.fira.worker / [FIRAPBMeasurementBundle initWithMessageInfo:]

[frunny]

Xcode version: 8.3.3
Firebase/Auth (4.1.1):
Firebase/Database (4.0.2):
Firebase Product: Auth and Database

So far we can't reproduce the problem. It happens on many devices since we updated to Firebase 4.1.1.

I can only say that we have a lot of other crashes as well and I have no clue why.

• FIRAMeasurement
• FLeafNode initWithValue:withPriority
• FSnapshotUtilities nodeFrom:priority:withValidationFrom:atDepth:path
• GAI threadMain
• FSnapshotHolder init
• FIRInstanceID
• FIRASqliteStore

We don't do much with firebase for now. We just auth a user as anonym and write two numbers to the user database. On app launch we read back one of the numbers. So nothing special here. We never could reproduce this problem on our production machines. We even get sometimes users with a NULL as userID.

Attached is the crashlog.

The attached crashlog indicates FirebaseAnalytics

[frunny]

Mh, we only use:
pod 'Firebase/Core'
pod 'Firebase/Auth'
pod 'Firebase/Database'

But we ran Google Analytics at the same time. Could this lead to problems?

[paulb777]

The Firebase pods have a dependency on FirebaseAnalytics. You'll see it being pulled in if you look at Podfile.lock.

It should be fine to include Google Analytics at the same time.

[frunny]

Ah I see it - thanks! Any idea why we get all those crashes? We have problems with Firebase from the beginning but the last 4.1.1 update brought in even more problems.

[frunny]

We are now getting new crashes from firebase coming in every few minutes.
Latest are:
[FIRASqliteStore recordsForQuery:parameterValues:error:withFilter:]
[FIRASqliteStore endTransaction]
[FSnapshotUtilities nodeFrom:priority:withValidationFrom:]
[FSnapshotHolder updateSnapshot:withNewSnapshot:]
[FSnapshotUtilities nodeFrom:priority:]

[baolocdo]

thanks for reporting. Can you please provide the content of the Podfile.lock? Thanks

[frunny]

Here is the Podfile.lock
Podfile.lock.txt

[paulb777]

@frunny Thanks! Will you confirm that the Podfile.lock.txt attached is the one used for the app build that created the crashlog attached to the initial bug report with the crash in com.google.fira.worker?

[frunny]

I did some pod update meanwhile but there was no update available.
So yes, it's the one with the crashes.

[morganchen12]

This crash (the one with the stacktrace in the original post) is occurring in some low-level pb-copying logic. It's going to be really difficult to pin down the cause without repro steps or a ton of information, which is why this issue has stagnated a little bit. The exception/crash message and code seem to be missing from the crash log--can you post them here? By crash message I mean whatever the mach message or signal is (i.e. EXC_BAD_ACCESS/SIGABRT) and the code shoul dbe some hex number next to the message (i.e. 0x8badf00d).

[morganchen12]

@frunny is this crash still occurring in newer versions of Firebase?
