There will clear the BSS in the function clear_bss(), the reset address of the BSS started from the __bss_start, and increased by four-byte increments, finally stoped depending on the adress is equal to the _bss_end. If the end address __bss_end is not alignment to 4byte, it will be an infinite loop.
The end address of the bss should be 4byte aligned.
