I allocated a large stack space for a task. Part of that task is defined as a char array. In the task a xQueueReceive is called waiting for a pointer to data. The pointer memory is copied to the char array. When I read out the character array after the copy, all I get are a bunch of A5 which is not what I'm expecting. Is the stack space marked A5s?

Task stacks are filled with 0xa5 before the task is started.
