Omar Sandoval faad25d7b2 libdrgn: debug_info: fix address of objects with size zero ... The stack trace variable work introduced a regression that causes objects with size zero to always be marked absent even if they have an address. This matters because GCC sometimes seems to omit the complete array type for arrays declared without a length, so an array variable can end up with an incomplete array type. I saw this with the "swapper_spaces" variable in mm/swap_state.c from the Linux kernel. Make sure to use the address of an empty piece if the variable is also empty.
