We also meet such crash for UIWebView since iOS 10.3.0 randomly in Fabric. It seems there is any thread related issue like race condition in storage thread, which cause m_storageMap of StorageAreaImpl corrupted

Does the crash happens due to webkit source bug? I want to get some ideas to solove the crash.
