digitalPulse() on stm32f3discovery

I have an error on my "stm32f3discovery" card that I have detected when I make some "digatalPulse ()" after another.
If I make a digital pulse that is greater than 1004, and after that has a digital pulse big or small, I get the error.

The last digital pulses in the series, may well be greater than 1004.

Software version 1.39.

My function: without error

function te () {

   digital pulse (LED1, 1500)

   digital pulse (LED3, 1.1004)

   digital pulse (LED5, 1.2000)

/ / Digital pulse (LED7, 1200)

}

My function: with errors

function te () {

   digital pulse (LED1, 1500)

   digital pulse (LED3, 1.1005)

   digital pulse (LED5, 1.2000)

/ / Digital pulse (LED7, 1200)

}

And the error:
