Teensy LC, SnoozeTimer never wakes

[ShuffleBit]

First off: I appreciate your contribution, even if this can't be fixed.

Simple code test on a Teensy LC. Nothing is connected to the LC, however it is powered by Vin, so the USB/Vin jumper on the bottom of the LC is cut, 5.03V power is supplied on Vin, and USB is connected. The call to Snooze.sleep() never returns. I tried deepSleep() also, the only difference being that the USB port goes away when the LC enters deep sleep. I believe it's supposed to wake up after 500ms. It doesn't. The code:

`#include <Snooze.h>
#include <SnoozeBlock.h>

const int ledPin = 13;

SnoozeTimer timer;
SnoozeBlock my_config(timer);

void setup() {
pinMode(ledPin, OUTPUT);
timer.setTimer(5000);// milliseconds
delay(5000); // Because otherwise, we can't ever program it again
}

void loop()
{
digitalWrite(ledPin, HIGH);
delay(10);
digitalWrite(ledPin, LOW);
Snooze.sleep( my_config );
}`
