System Workbench for STM32

I am getting a hardfault issue when calling the printf function. Please find the attached details

Call stack
Thread #1 (Suspended : Signal : SIGINT:Interrupt)
prvGetRegistersFromStack() at stm32f1xx_it.c:109 0x800441a
() at 0xfffffff9
std() at 0x8007abe
__sinit() at 0x8007b76
printf() at 0x8006dac
main() at main.c:130 0x800400c

From the NVIC register CFSR, I could see that BFARVALID and PRECISERR are set. Also the content of BFAR is 0.
