It seems that the DWT CYCCNT does not advance when the CPU waits on a WFI instruction. That leads to the effect that for example on the atsamv BSP a sleep(1) needs something in the range of a few minutes (depending on the configured systick). A debugger might disables some deep sleep modes so that the problem only appears if the application is executed without a debugger.
