What is stack in GDB?

All the stack frames are allocated in a region of memory called the call stack . When your program stops, the GDB commands for examining the stack allow you to see all of this information. One of the stack frames is selected by GDB and many GDB commands refer implicitly to the selected frame.

Is stack limited in size?

It is just a default size. If you need more, you can get more – most often by telling the linker to allocate extra stack space. The downside to having large stacks is that if you create many threads, they will need one stack each.
