Try this:

#include <iostream.h>

void  PrList (int stopval)
{       int x = 1;
        while (1)
        {       if (x >= stopval) throw "Out of bounds";
                cout << x++ << endl;
        }
}

int  main (void)
{       try {  PrList (10);  }
        catch (char *msg) {  cout << "char* catched: " << msg << endl;  }
	catch (const char *msg) { cout << "const char* catched: " << msg << endl; }
        return 0;
}

and You'll see the source of problem ...
