c++ - Is it possible to catch a segfault with try/catch?

I did this test to see what happened:

try
{
    int *x = 0;
    *x = 1234;
}
catch(...)
{
    cout << "OK";
}

But it throws a segfault, why does it not catch the segfault?

No you can`t.

A SEGFAULT isn't a regular exception.

The code you show is simply undefined behavior, and anything may be happen. There's no guarantee it ends up throwing an exception.
