EXC Bad Access on conversion to string/ access violation

#include <iostream>

using namespace std;

    }
  
    vector<int> splitter(){
        
        
        string strin = to_string(number);
        
        for (int i = 0 ; i < strin.length(); i++) {
            
            
            int convert = charToInt(strin[i]);
            
            if (convert > 0){
                splitter().push_back(convert);
            }
            
        }
        
        return splitter();
        
    }
    
};


int main(int argc, const char * argv[]) {
    
    
    vectorPrint(Numbas(23040502).splitter());
    

    
}

I have no idea how to solve this, it keeps throwing the Access Violation writing location 0x01240FFC code at me.

Any help would be greatly appreciated, I've been stuck like this for hours now :'D

After fixing the typos (change the two occurrences of Numbas to numbas),
the microsoft compiler with -W4 -analyze reports:
