Ha!
And one would think that binutils would've seen the ".quad 0" in the
previous definition and do a proper size but that wouldn't have worked
most likely, because before it was a simple label with alignment:
.globl saved_magic ; .p2align 4, 0x90 ; saved_magic: .quad 0
which didn't have a size probably because it didn't have an associated
type (or an implicit default type or so, no clue how binutils handles
labels).
VS now:
.globl saved_magic ; ; saved_magic: ; .quad 0 ; .type saved_magic STT_OBJECT ; .size saved_magic, .-saved_magic
