So that was a loaded subject line. I'm creating a port of webkit called
webkit.js (http://github.com/trevorlinton/webkit.js). So far i've been
fairly successful at compiling in both Release / Debug modes. I've been
able to incorporate all of webkit's dependencies
(freetype/fontconfig/cairo/etc..) and for months haven't had many issues
(at least, not with emscripten). But as of recent i've began working in
Debug mode because of its lovely stack traces that are incredibly helpful.
I went to do a recompile in Release mode and have been experiencing some
weird errors, if I remove -O2 from the command everything works fine, add
it back in, and I get these errors:

Does anyone know off hand what might be the issue? Is there any hugely
concerning issues with the build log (other than some missing/unresolved
symbols)? I should note that in Debug mode it compiles and runs (well
there are issues, but unrelated to emscripten).
