I came to know that smart pointer is used for resource management and supports RAII.
But what are the corner cases in which smart pointer doesn’t seem smart and things to be kept in mind while using it ?

Smart pointers don’t help against loops in graph-like structures.
For example, object A holds a smart pointer to object B and object B – back to object A. If you release all pointers to both A and B before disconnection A from B (or B from A) both A and B will hold each other and form a happy memory leak.
Garbage collection could help against that – it could see that both object are unreachable and free them.
