i'm not sure if you're just literally dumping code in or what, but
something like

	acid: dump(0xdfffefb4, 4, "I")
	0xdfffefb4: SHRB	$0xff,BH
	0xdfffefb7: FMOVW	0x0(AX),F0
	0xdfffefb9: ADDB	AL,0x0(AX)
	0xdfffefbb: ADDB	AL,0x0(AX)
	0xdfffefbd: ADDB	AL,0x0(AX)

will bypass the fiddling with the executable that is causing you trouble.
