Everything from wheezy/sid, and I'm not using gold. I don't even have
gold or GCC 4.5+ installed.

gcc version 4.4.5 (Debian 4.4.5-12)
GNU ld (GNU Binutils for Debian) 2.20.1-system.20100303

Not really, didn't try that. It actually surprised me because I
thought the DSO linking change wouldn't affect sid for a while after
the Debian freeze, but it seems to be already in place somehow.
Several other packages are failing to link in sid now because of this.

Yep, not only X packages, a lot of stuff will break, mostly minor bugs
like this, but there will be false positives as well (lots of things
that use Boost, for instance).

It could be. Regardless, this bug isn't Debian specific and affects
all distros as they move on to --no-add-missing or gold.
