Re: [Dev-C++] Catching illegal pointer access

I just forgot to mention, depending on what you want to do, you can use 
signals. Obviously signals are used in a very different way than 
exceptions, but may be useful if all you want is to dump some 
information before the crash. See the example:

----
#include <iostream>
#include <csignal>
#include <cstdlib>

using namespace std;

void foo(int signum)
{
        cout << "Program crashed... press enter to finish" << endl;
        cin.ignore();
        exit(EXIT_FAILURE);
}

int main()
{
        signal(SIGSEGV, foo);

        int *a = 0;
        *a = 1;

        return EXIT_SUCCESS;
}
----

But quoting ISO/IEC 9899:1999, page 245:
"An implementation need not generate any of these signals, except as a 
result of explicit calls to the raise function. (...) The complete set 
of signals, their semantics, and their default handling
is implementation-defined (...)."
