gdb 调试遇到 Cannot find bounds of current function

在写一个小型的操作系统内核，使用go语言，plan9汇编中有如下代码：

TEXT ·sys_clone(SB), NOSPLIT, $0
	MOVL $SYS_clone, AX
	MOVL pc+0(FP), DX
	MOVL stack+4(FP), CX
	INT  $0x80

	// In parent, return.
	CMPL AX, $0
	JEQ  3(PC)
	MOVL AX, tid+8(FP)
	RET

	NOP SP // tell vet SP changed - stop checking offsets
	JMP DX

当下一句是INT $0x80时，继续next或者step就会遇到问题：

求助大家，帮帮孩子吧！

刚进去调试的时候没有异常，但step到INT $0x80的时候突然就 “cannot find bounds of current function”。
