Code Sample

...
NSInteger const kDatabaseVersion = 1;
...
- (void)configureDatabase {
    RLMRealmConfiguration *config = [RLMRealmConfiguration defaultConfiguration];
    config.schemaVersion = kDatabaseVersion;
    config.migrationBlock = ^(RLMMigration *migration, uint64_t oldSchemaVersion) {

        if (oldSchemaVersion < kDatabaseVersion) {}
    };

    [RLMRealmConfiguration setDefaultConfiguration:config];

    [RLMRealm defaultRealm];
}

or I just try to add new item to Realm:

        @try {
            RLMRealm *realm = [RLMRealm defaultRealm];
            [realm beginWriteTransaction];
            [realm addObject:pair];
            [realm commitWriteTransaction];
        }

Version of Realm and Tooling

I'm using Pods: Realm (0.98.4)

Hi @alychkouski, I took the time to create a project with your sample code and haven't been unable to reproduce the issue you've reported: https://github.com/jpsim/GH3316

Could you please either let me know what my repro case is missing to trigger the problem you've reported, or better yet, send us a full Xcode project that triggers the issue?

Thanks!

I think I'm having the same issue. I've added Realm to my project via CocoaPods with the use_frameworks! option on (might be important, probably?) and anytime I access the database, Realm would crash with EXC_BAD_ACCESS (code=EXC_ARM_DA_ALIGN). Also, I didn't observe this behaviour just during database configuration or entry updates – even the simplest queries would crash Realm completely.

Downgrading to 0.98.2 “solved” the issue for me. I will try to replicate the issue in an empty project this evening.

Added pull request to the jpsim/GH3316 repository with changes to force the test project to crash. However, I didn't realise that the 0.98.5 version was released just a few days ago, 0.98.5 is definitely fine and not affected by the issue, at least not for me. 0.98.4 was throwing the same errors as the reporter had for me, but 0.98.5 is fine.

This is the same crash as #3321 and was fixed in v0.98.5.
