Bus fault in the below program

#include<stdio.h>
#include<stdint.h>
#define SCHED_STACK_START 20126976U
void init_tasks_stack(void);
void task1handler(void);
void enable_processor_faults(void);
 
__attribute__((naked)) void init_scheduler_stack(uint32_t sched_top_of_stack);
 
int main(void)
{
 enable_processor_faults();
 
 init_scheduler_stack(SCHED_STACK_START);
 
 task1handler();
 for(;;);
}
 
__attribute__((naked)) void init_scheduler_stack(uint32_t sched_top_of_stack)
{
 __asm volatile("MSR MSP,%0": : "r" (sched_top_of_stack) : );
 __asm volatile("BX LR");
}
void task1handler(void)
{
 while(1)
 {
 printf("In task1 handler\n");
 }
}
 
void enable_processor_faults(void)
{
 uint32_t *pSHCSR = (uint32_t*)0xE000ED24;
 
 *pSHCSR |= ( 1 << 16); //mem manage
 *pSHCSR |= ( 1 << 17); //bus fault
 *pSHCSR |= ( 1 << 18); //usage fault
}
 
 
void HardFault_Handler(void)
{
 printf("Exception : Hardfault\n");
 while(1);
}
 
void MemManage_Handler(void)
{
 printf("Exception : MemManage\n");
 while(1);
}
 
void BusFault_Handler(void)
{
 printf("Exception : BusFault\n");
 while(1);
}
 

I am trying to execute above code

if

 init_scheduler_stack(SCHED_STACK_START);

is commented out then, no problem in the code else there is bus fault

The fault analyser window throws error:

* Precise Data Access Violation

* Stacking error.
