Yes it is a bug. In compatibility code that was supposed to handle mixing old object files that use dot-symbols on function entry with newer object files that don't. Here, "old" means mid 2004 or earlier. As you can imagine, I'm not hugely concerned about the ld bug.. Since every binutils back to at least 2.17 has the bug, what changed in the kernel to expose it?
