I have just found a bug in sozobon top:-

If dlibs is compiled with the -O flag then the library becomes completely broken

If sprintf.c is compiled with cc -S -O sprintf.c then the following code is
produced:-

_sputc:
	link	a6,#0
	move.l	10(a6),a0
	move.l	(a0),a0
	addq.l	#1,(a0)
	move.b	9(a0),d0
	move.b	d0,(a0)
	ext.w	d0
	unlk	a6
	rts

If compiled without the optimiser switch then the following code is produced:-

_sputc:
	link	a6,#0
	move.l	10(a6),a0
	move.l	(a0),d0
	addq.l	#1,(a0)
	move.l	d0,a0
	move.b	9(a6),(a0)
	move.b	(a0),d0
	ext.w	d0
	unlk	a6
	rts

Is there a fix for this bug. (I wont fix(I'm not an expert at C))

Luke.
