Getting to the bottom of it

Getting to the bottom of it

The latest changes to Blunt 2 fixed the crash when sending a large number of data blocks, which was caused by memory management issues around the TUPort class used for communication between the tasks in Blunt. More specifically, the allocation and deallocation of memory for the messages was causing problems. I still need to find the right approach though, and it is probably best done via a small test program which uses tasks, shared memory, messages and ports.
