The Bug
While developing Bytecoin Wallet for OS X we've faced a bug in pthread library condition variable implementation. This bug can't be called nothing else but pesky. Pthread is one of the cornerstones of multithread programming and used in almost every OS X application that uses multithreads, including gcc, clang, java and boost. Due to this bug - user can lose a vital piece of data that is placed in the memory. For instance, some applications are storing transaction amounts in the memory and in certain circumstances this bug can lead to the data corruption and therefore some info regarding the transaction amount is going to be lost.
