[REQUIRED] Step 2: Describe the problem

A random crash of the app that uses the firebase SDK.

Steps to reproduce:

EXC_BAD_ACCESS: remoteConfigFlags > sessionCreationTime > sessionLengthInMinutes >
Attempted to dereference garbage pointer 0x43b8c8b79110.
File "FirebasePerformance/FirebasePerformance/Sources/AppActivity/FPRSessionDetails.m", line 43, in -[FPRSessionDetails sessionLengthInMinutes]
File "FirebasePerformance/FirebasePerformance/Sources/AppActivity/FPRSessionManager.m", line 78, in -[FPRSessionManager renewSessionIdIfRunningTooLong]
File "FirebasePerformance/FirebasePerformance/Sources/FPRClient.m", line 246, in -[FPRClient logGaugeMetric:forSessionId:]
File "FirebasePerformance/FirebasePerformance/Sources/Gauges/FPRGaugeManager.m", line 184, in __69-[FPRGaugeManager prepareAndDispatchCollectedGaugeDataWithSessionId:]_block_invoke_2
...

Relevant Code:

• (NSUInteger)sessionLengthInMinutes {
  NSTimeInterval sessionLengthInSeconds = ABS([self.sessionCreationTime timeIntervalSinceNow]);
  return (sessionLengthInSeconds / 60);
  }

Don't know how to reproduce.
