Detecting that the stack is full in C/C++
- by Martin Kristiansen
When writing C++ code I've learned that using the stack to store memory is a good idea.
But recently I ran into a problem:
I had an experiment that had code that looked like this:
void fun(unsigned int N) {
float data_1[N*N];
float data_2[N*N];
/* Do magic */
}
The code exploted with a seqmentation fault at random, and I had no idea why.
It turned out that problem was that I was trying to store things that were to big on my stack, is there a way of detecting this? Or at least detecting that it has gone wrong?
