Are you sure it's not just taking "a long time"? If that build machine
doesn't have enormous amounts of memory you could end up with a link phase
that takes tons of time for projects like clang or chrome.
Try linking a minimal case. If the bug you describe were there it should
reproduce easily (maybe once you get up to enough object files or sections,
whatever it's iterating over).
