Use of the dynamic data structures is a common technique used in all bigger software systems. On the other hand, searching for errors in such systems is very complicated thanks to the fact that the data structure itself is hidden behind the tricky pointer manipulations. Hence the automated methods for such programs are greatly welcome. The whole verification problem is much more complicated in the case, where several concurrent processes use a shared memory. Bad interference of one of these processes into a dynamic data structure inside the shared memory can interferes the other processes. Another complication for the verification is recursive functions calls. Despite of the huge progress in this area, a reliable verification tool for common use is still far away. Therefore the goal of the proposed basic research project is development of methods for this class of programs.
