Simulator suddenly crashing on DBFileSystem

I'm using the newest IOS SDK for the Sync API. All of a sudden I'm getting a EXE_BAD_ACCESS when trying to assign the DBFileSystem as follows: (crashes on DBFilesystem *filesystem = [[DBFilesystem alloc] initWithAccount:account];). I'm using Xcode 6.1 and both the 71 and 8.1 simulators are crashing.

DBAccountManager *accountMgr =
[[DBAccountManager alloc] initWithAppKey:appKey secret:appSecret];
if (accountMgr) {
    [DBAccountManager setSharedManager:accountMgr];

    // Set up main linked account
    int nAccounts = [[accountMgr linkedAccounts] count];
    if (nAccounts > 0) {
        DBAccount *account = [[accountMgr linkedAccounts] objectAtIndex:0];
        if (account) {
            DBFilesystem *filesystem = [[DBFilesystem alloc] initWithAccount:account];                
        }
    }

    Yes but unfortunately it makes it virtually impossible for me to test my app on devices that I don't have without having to move it back and forth all the time to my laptop. Just a colossal pain is all :). Thanks for all your help - I will let you know if the problem suddenly goes away due to an update or something ...

    Another clue :). I'm currently upgrading the app to 64-bit. As soon as I do that it now crashes on the device as well as the simulator. Previously I guess the simulator was the only thing using 64-bit. Now that it crashes on the device though I have a nice crash report for you which may be more useful in trying to figure this out ...

    We looked over this again, and there certainly seems to be something unusual going on, but unfortunately we won't be able to investigate without reproducing it. Do you know if there's anything unusual about your app's configuration? The best thing to help here would be if you could reproduce this in a sample project you can send us. Maybe there's something about the configuration unique to your app you could replicate.

    Also, what device(s) have you seen and not seen this on?

    Darn - was hoping for an easy solution :). The only thing unique about our configuration is that we do use several 3rd party frameworks and libraries including ArcGIS, GDAL and all it's support libraries. I'm wondering if one of their or one of my headers has a conflicting setting as the app actually doesn't invoke anything much before this happens as in the application launch where it fails. I will have to do this the hard way and start removing stuff from the app until it works again or is a reasonable size that you can look at.

    I did have to modify the linker flags to the following "-ObjC -framework ArcGIS -l c++"

    I've currently seen this on all the devices that I have - iphone4s, iphone6 and iPad air and of course the simulator.

    Thanks for the information. I was able to reproduce the crash by adding ArcGIS. :-)

    We'll investigate it using this reproduction.

    Just wondering if there is any progress on this. We are trying to establish a timeline to have a 64-bit version of the app (before Apple's deadline) and need a solution to this problem before we can create the 64-bit version.
