FreeRTOS--stack experiment

In FreeRTOS, when a task is created, the pvPortMalloc function is called to allocate the task TCB structure and stack space similar to malloc.

The complete space requested by the task on the heap is as follows:

The header contains some information in the latter part, such as length information.
Task 1 has applied for 100 bytes of stack space, but if the internal use of task 1's stack space exceeds the 100-byte space it applied for, then the information in front of the stack space of task 1, such as header data orThe data in the TCB structure will be destroyed, and the program will crash.
So when creating a task, make sure that the stack space allocated to the task is large enough.
