Problem with my own linker script

Hi everyone
I have problem with my linker script, i want to setup position of my own vector table, stack and heap by myself using C++. Everything seems to be ok until program invoke fun.blink() function and try to heck value of pin_state variable, when this is happen program immediately jump to HardFault_Handler_IRQ.

Im using ARM v6.12 compiler
