LLE10209 : Howto create a stack overflow on purpose in C/C++

Symptom:

You want to produce a stack overflow to learn to know your system better

Cause:

none

Solution:

There are quite some possibilities to create a stack overflow and it just takes a second to reach it.

Stack overflow can be done with
1. Infinite recursion with functions
2. very large stack variables
3. through exhausting other shared memory e.g. (windows Desktop Heap Size) can lead to stack overflow errors!

Infinite recursion can be programmed like:

 void a() {
   a();
 }
 int main() {
   a();
   return 0;
 }


or like

 void f(void);
 void g(void);
 
 int main(void) {
   f();
 
   return 0;
 }
 
 void f(void) {
   g();
 }
 
 void g(void) {
   f();  
 }


Excessively large stack variables can be done with:

 int main(void) {
   double n[10000000];
   return 0;
 }
