Timer ses causes LPC812 lockup

I have a very simple blink program that is implemented using wait_ms and Timer. The wait_ms version (f2) works as expected while the Timer based version (f1) works for around 70 seconds and stops, i.e. the LED stops blinking.

What am I doing wrong with the Timer based code?

#include "mbed.h"

DigitalOut ledpin(P0_14);

void f1() {
  Timer ledtimer;
  for (;;) {
    ledpin = !ledpin;
    ledtimer.reset();
    ledtimer.start();

    while(ledtimer.read_ms() < 500);
  }
}

void f2() {
  for (;;) {
    ledpin = !ledpin;
    wait_ms(500);
  }
}

int main(void) {
  //f1();
  f2();
  return 0;
}
