In that case it shouldn't be because of a wrong -fvisibility option, I think.

Do you have the possibility to test with an earlier version, gcc 5.x or even 5.4? Normally I'd say this shouldn't be necessary, but gcc 6 is still new enough not to exist everywhere AFAIK, and I've been seeing a bit too many commits related to gcc-6 compatibility lately.

The manpages for OS X are available online just like they are for Linux ;)

I'm seeing -fvisibility=hidden -fvisibility-inlines-hidden but they're set automatically and are used almost everywhere. Apparently not in debuggers/gdb, though.

That may in fact explain the issue, maybe debuggers/gdb contains something that causes it to be built with default (public?) visibility and you then moved things to debuggers/common without ensuring that part is built with the same visibility rules.
But that wouldn't explain why EditorContext::currentWord() and the EditorContext typeinfo are the only symbols concerned...
