Stack traces when stack overflow

This crashes at runtime because of a stack overflow, without stack frame or error message (DMD 2.053), no stack trace, or line number are shown:
int foo(int n) {
return n ? foo(n - 1) : 1;
}
void main() {
foo(100_000);
}
If you aren't running a debugger then receiving a nude crash is not so nice, because in a larger program there are many functions that may be the cause of such stack overflow. So is it possible to add some stack protection code (in non-release mode only, if necessary) to receive a stack trace in this case?
