crash after upgrade from 0.92.3

[pengj]

Hi,

After upgrade from 0.92.3 (RealmSwift) to 0.92.4 or 0.94.0, app crashed at the same place when call let realm = Realm()

This crash occurs only when running on the devices. (No crashes occur on the simulators iOS 8.4)

Environment:

iOS 8.1.3 iPhone 5 Xcode 6.4 RealmSwift (0.92.4 to 0.94.0)

There is no output, only (lldb)

@pengj are you sure it's not an exception being thrown, with a message? If not, having a project we can run would make investigating much easier, thanks!

I also have crash on launch with version 0.94.0 Link to the crash http://crashes.to/s/ab443d71878

@Armenm that crash looks like https://github.com/realm/realm-cocoa/issues/2332, and does not look like @pengj's crash.

Thanks @segiddins for quick reply. Will comment there. Maybe it will help to fix the bug.

@segiddins There is no exception message being thrown when app crashed, the screenshot shows the moment when app crashed. I try to make a simple project to reproduce the error, but I can't reproduce it.

[pengj]

@segiddins When I configure the app build as release, there is no crash.

if build in debug, the crashed happen here:

@objc private class func indexedPropertiesForClass(type: AnyClass) -> NSArray? {
        if let type = type as? Object.Type {  <---- with error: `EXC_BAD_ACCESS(code=1, address = 0xc)`
            return type.indexedProperties() as NSArray?
        }
        return nil
    }

@pengj in that case, since it's actually the swift standard library crashing and not Realm, and since you can't reproduce it, I'm going to close this issue for now. Feel free to re-open it if you see this happening again!

[pengj]

@segiddins see my updated comments

[segiddins]

Can you share the project with us so we can investigate? Thanks!

[pengj]

@segiddins I sent you a email with my project. Thanks for your help.

[segiddins]

@pengj I can't reproduce this on the iPad Mini 2 I have at hand. Are there any specific steps I need to take in order to see the error?

[pengj]

@segiddins the app crash when test in iPhone5 with iOS 8.1.3, it works for iPad air with iOS 8.4.

[segiddins]

@pengj I don't have an iOS 8.1.3 device around, but it worked fine on a 32 bit iPod touch running 8.3.

@segiddins I will close the issue for now. The crash only happens on iPhone 5 with iOS 8.1.3 as far as I can see, works well for simulator with iOS 8.1. If the build is configure as release rather than debug, it also works well. Let's wait if other developers have the same problem when update. Thanks for your help.
