RL-RTX and RL-FlashFS ->DAbt_Handler

Hi,
Use: MDK-ARM V4.14, RL-ARM V4.13 Processor: LPC2478 (MCB2470).
The Code of the program:

__task void task_main (void)
{
        finit();// =>DAbt_Handler
        os_itv_set(100);
        while(1)
        {
                os_itv_wait ();
        }
}
int main (void)
{
        os_sys_init(task_main);
        while (1);
}

When calling the functions processor finit() leaves in interruption DAbt_Handler.
In project is connected Retarget.c., Size Heap = 2048. The Mode MicroLib out-of-work.
Unless use RL-RTX, that RL-FlashFS works orderly.
