In any case, have you tried this? Works on unixen only.

   ...

Not sure if it prints a stack trace on a stack overflow, 
however.

Update for anyone reading this old thread:

You need to add `nothrow @nogc @system` to `handleSegv`.

```
import core.stdc.signal;

nothrow @nogc @system
extern(C) void handleSegv(int) { assert(0); }

shared static this() {
        signal(SIGSEGV, &handleSegv);
}
```

This answer worked great for me.
