OS memory
What is the maximum size of the stack?
It depends on your operating system. On Windows, the typical maximum size for a stack is 1MB, whereas it is 8MB on a typical modern Linux, although those values are adjustable in various ways. If the sum of your stack variables (including low-level overhead such as return addresses, stack-based arguments, return value placeholders, and alignment bytes) in the entire call stack exceeds that limit, you get a stack overflow, which typically takes down your program without any chance at recovery.
