You are right, node->next is always equal to NULL, but it's not a bug, the author just did not use it.
Because you actually can implement a stack with only one pointer to next node (prev or node in that case is a semantic issue), like singly linked list.

@zphiliam thank you for reporting the issue.
well node->next being NULL is not a bug, but due to this

b1fed3cf3e/data_structures/stack.c (L111)

this line becomes useless.
