Well, that can happen. Stanislav from the support team told me that they work on it and will release a new build next week. In the meantime, don't update your terminal. If you already have, you can switch back to previous version by replacing the terminal.exe file with an older version.
I just wrote about on my blog. Here is the link to the post: http://pipburner.com/metatrader-build-418-bug-alarm-how-to-switch-back-to-previous-version/

I have lost some money with this changes, I have customers that had lost a hugh amount of money because this situation! I don't know what metaquotes think about customers who are using their platform and losing money! This is not professional work! How they will work to recover the money that customers all around the world are losing or lost until discovered this issue???
Double returned by external function as functional result does not work at all. Double parameters passed as argument are working.
What QA process is established in Metaquotes that somebody can release in production such fundamental error which may cause money lost !!! Thumbs down.
