LPTMR not working in Release mode (K64)

While working on the FRDM K64 I've noticed a strange behaviour; I've defined the blue led to toggle while working, among other functions which needs interrupts (using the example in the LPTMR driver source code). It toggles when working under Debug mode. In Release mode it does not. Obviously, the interrupt is not sent, which makes me wonder, whether the PIT interrupt (which I use for other functions) is not working also in Release mode?

Anything I can do to make it work under Release mode also?
