This can happen when LogHandler::flushRepetedMessages is called on the main thread, while the application is printing messages on a separate thread. The access to the _lastRepeatedMessage QHash was not guarded. I've added two mutexes to guard access to both the repeatedMessage hashes/regexes and the onlyOnceMessages/regexes. This will unfortunately incur a performance hit for frequent debug logging, but that's better then crashing. Also, I've added the ability to print threadIDs as well as Process ids. This is helpful when debugging multi-threaded access to shared variables. |
