When an attempt to dereference the game_position_pointer is made, just like at this function:
update_draw:
mov rbx, [game_position_pointer + rax]
mov rsi, player
cmp byte[rsi], "0"
je draw_x
cmp byte[rsi], "1"
je draw_o
draw_x:
mov cl, "x"
jmp update
draw_o:
mov cl, "o"
jmp update
update:
mov [rbx], cl <- Here the problem
ret
It lead us to a segmentation fault.
PS: The game_position_pointer is a quadword array that holds the address of each house of the board, but it seems that it loses all its addresses after the call to clear_screen function, so the failure.
