medium📝 Debug Q14 of 15
Step-by-Step Solution
Solution:
Step 1: Understand heap_3 implementation
heap_3 uses standard malloc() and free() from the C library for memory management.Step 2: Identify conflict cause
If other parts of the system also use malloc/free independently, it can cause heap corruption due to overlapping or mismatched management.Final Answer:
Using standard malloc/free that conflicts with FreeRTOS allocations -> Option AQuick Check:
heap_3 uses malloc/free which can conflict [OK]
Quick Trick: heap_3 uses malloc/free; conflicts cause corruption [OK]
Common Mistakes:
- Assuming heap_3 manages memory independently
- Forgetting to define configFRTOS_MEMORY_SCHEME
- Thinking heap_3 requires manual defragmentation
