Same issue on my end. Mac Air Yosemite

I solved this by using brew uninstall libiconv. Notice this may make anything you use libiconv (like Nokogiri for Ruby) break.

OpenBSD is suffering from this exact same issue.

EDIT: Should be more specific. OpenBSD 5.9 tracking -stable is also having this issue. I thought for a minute that it may be caused by the fact that I performed a 'downgrade' by changing from tracking snapshots to tracking -stable on 5.9's release, but forcing a reinstall of libiconv from upstream hasn't fixed the issue.

What's more - I can't get the libiconv package for OpenBSD to uninstall without having a bunch of other packages go with it. (python, zsh and emacs being some big ones :P) This means that @rushingfitness's solution won't work here - even temporarily - unless I want to reinstall those dependent packages too.

What is going on here? I can't seem to build with gcc. How can I fix this.
