Abstract: One embodiment of the present invention relates to a system for efficiently annotating numerous crash reports originating from multiple instances of an application. Prior to deploying a version of the application, a service receives a file that stores debugging information associated with the version. Next, the service parses the debugging information from the file. The service then converts the debugging information into an object representation in memory and stores the object representation in a database. Next, in response to an instance of the version crashing on a client device, the service receives a crash report from the client device. Then, for each item in the crash report, the service determines whether that item needs to be annotated and, if so, annotates the item.
