sram [push,--,head_offset,base,4];the pointer's linked-stack[4] elements[0] is 0x1

sram [push,--,head_offset,base,4];the pointer's linked-stack[4] elements[1] is 0x2

sram[pop,$xfer0,dummy,0,4];$xfer0:=0x3
;SHOULD BE sram[pop,$xfer0,--,--,4],the compiler maybe has BUG !!!
sram[pop,$xfer1,dummy,0,4];$xfer1:=0x2
sram[pop,$xfer2,dummy,0,4];$xfer2:=0x1
sram[pop,$xfer3,dummy,0,4];NOTE:in case of the problem of stack exhaustion , the pointer of stack end should point to itself.
