We are seeing this in gentoo on x86_64 with gcc-4.9. See

What's confusing me is that some of our users are seeing this bug and others
are not. This leads me to think maybe its a c++ abi mismatch because we do
allow our users to build their systems using any recent version of gcc (and c++
abi emitted by 4.8 is not compatbile with that emitted by 4.9). However, that
fact tat removing -fvisibility-inlines-hidden fixes this argues against my
suspicion. So why would some of our users it this and others not?
