working on a 32bit architecture and i'm adding two arrays together slot by slot into a third array so if I have 3,4,4 and 4,4,4 in the arrays the third array should contain 7,8,8 at the end of the function

I was able to pass in the arrays correctly and the amount of items into the function arleady, i know this because I ran test code

now i'm working on the addition part of it, here is what I have, the logic makes sense to me but it's still seg faulting...ideas?

segment .bss
segment .data

segment .text
extern readdouble,print_string, read_int, writedouble, print_nl, print_int
	global addarray
	mov	edi, 0		;initialize counter to 0
	mov	ecx, 0		;zero out ecx and edx
	mov	edx, 0
	mov	ebx, [esp+48]	;moves starting location of array1 into ebx
	mov	edi, [ebp+40]	;move quantity into edi	
	mov	ebp, [esp+60]	;move the starting location of array2 into ebp
	mov	esi, [esi]	;move starting locatino of array3 into esi
	;mov	ecx, [ebp]
	;mov	edx, [ebp+4]
	;call	writedouble
	;call	print_nl


        fld     qword [ebx]      ;The second input is now in a floating point register, specifically st0.
	fld	qword [ebp]

	fadd    	         ;The first input is added to the second input and the sum
		                 ;replaces the second input in st0
	fstp	qword [ecx]	;copy top of stack onto ecx
	mov	ecx,[ecx]
	mov	edx,[edx+4]	
	mov	[esi], ecx
	mov	[esi+4], ecx
	add	esi, 8		;increment to the next loaction of esi
	add	ebx,8		;increment location of ebx to the next floating point value of array1
	;add	ebp,8		;increment location of ebp to the next floating point value of array2
	dec	edi		;increment counter

	cmp	edi, 0		;compare to see if all values have been added
	jz	add_done
	jmp	add_loop
