Linker lists rely on contiguous symbols laid out at consistent alignment. When the linker inserts padding the start/end pointer arithmetic silently produces garbage, leading to baffling runtime failures such as wildly negative test counts.
Add a small Python script that walks the linked u-boot image with nm -S, flags gaps that look like padding, and verifies that each list span is a whole multiple of its element size. Wire it into the Makefile so it runs after the final link.
