The second paragraph in this link on Abseil containers says:
For example, the Abseil containers often do not guarantee pointer stability after insertions or deletions.
What does pointer stability mean in this context?

Pointer stability means that the pointer is guaranteed to remain stable for the life of the object to which it points(i.e. the address the pointer points to remains constant and does not change), unless you do something to break it.
The virtual memory space the Operating systems presents to your process will keep things at the same addresses. Although the physical memory might change. This is one of the things OS has to take care.
