The interrupt: Cpu_ivINT_Hard_Fault

I am using the FRDM-K20D50M with the CMSIS-DSP library and getting the Cpu_ivINT_Hard_Fault  interrupt in the middle of the FFT routine arm_rfft_q31.

I'm not sure if this routine has anything to do with this interrupt.

Is there a way to disable this interrupt?

If not where do I start to trouble shoot this?
