What (who) is unwind the stack - definition
TREE DATA STRUCTURE IN WHICH EACH NODE HAS A POINTER TO ITS PARENT NODE
Cactus stack; Saguaro stack; Spaghetti stack
unwind the stack
During the execution of a procedural language, one is said
to "unwind the stack" from a called procedure up to a caller
when one discards the stack frame and any number of frames
above it, popping back up to the level of the given caller.
In C this is done with "longjmp"/"setjmp", in Lisp
with "throw/catch". See also smash the stack.

Call stack
STACK DATA STRUCTURE THAT STORES INFORMATION ABOUT THE ACTIVE SUBROUTINES OF A COMPUTER PROGRAM

In computer science, a call stack is a stack data structure that stores information about the active subroutines of a computer program. This kind of stack is also known as an execution stack, program stack, control stack, run-time stack, or machine stack, and is often shortened to just "the stack".

Parent pointer tree
In computer science, an in-tree or parent pointer tree is an N-ary tree data structure in which each node has a pointer to its parent node, but no pointers to child nodes. When used to implement a set of stacks, the structure is called a spaghetti stack, cactus stack or sahuaro stack (after the sahuaro, a kind of cactus). Parent pointer trees are also used as disjoint-set data structures.
The structure can be regarded as a set of singly linked lists that share part of their structure, in particular, their tails. From any node, one can traverse to ancestors of the node, but not to any other node.
