Crash on IOS with NativeAOT: help interpreting a stacktrace about realm-dotnet

[charlesroddie]

Thanks for the help here. I thought UInt64 since the generic argument of the regex was UInt64. We did notice that we were using IEnumerable around some realm returns which may have caused lazy access. After fixing this we are still getting a crash but without Realm mentioned. So I will close this issue and move it to dotnet/macios. The stacktrace does have System.Linq and it's possible that realm is calling this as the main user of System.Linq but I will close this for now unless realm reappears.

What version of Realm are you using?

Latest 11.6.1

So here are a few thoughts reading through the stacktrace:

1. Looks like at some point, this goes through the ctor for RealmCollectionBase<float?>.
2. The exact error happens when setting the Handle field which is a Lazy<CollectionHandleBase>.
3. What makes you think there's UInt64 involved? We definitely use this type when talking to the native layer and also the framework uses it quite a bit to represent pointers, but at no point will we ever parse it from a string.
4. The stacktrace doesn't make much sense to me as there's no clear reason why we would go from the ctor of the collection to an enumerator in 10Mathematics_EduTypes_RQLRecord. Either there's frames missing or I'm not seeing something.
5. The crash seems to be happening somewhere where you're iterating and selecting a kvp involving 10Mathematics_EduTypes_RQLRecord - might be worth trying to find where that is and share the relevant code to see if we can correlate it.
