EDITED TO ADD: Chrome Version 56.0.2924.87 (64-bit), OSX El Capitan 10.11.6

Comece carregando test.html com o GitHub.bundle.min.js referenciado no Chrome e rastreie a falha desde base64.js:89 passando por Requestable.js, Gist.js e GitHub.js. Verifique se o bundle pode ser inicializado sem o erro de expressão regular relatado; considera-se concluído quando GitHub estiver definido e o console não exibir mais esses erros.
