It's actually alarmingly common for Windows C/C++ apps to paper over crashes with SEH try { } catch (segfault) { /* seems to work */ } this way. Even Microsoft's own apps used to do it, maybe they still do. You run into this when running random apps under a debugger.

There's nothing structured about core dumps. Better to do nothing so the developer can see a clean core dump.
