Product Variations PHP55

Firstly, Ive been using GAE to run WP + WooCommerce, and I found an issue where they variable product types were not displaying variations. Upon investigation, I found the issue to be in the file:

… class-wc-product-factory.php on line 50

issue being:

… preg_replace(): Modifier /e is not supported.

I discovered a solution, however, it required me to modify the file.
I was wondering however, if someone was able to write a function which would fix this problem? Or even know when this issue would be fixed? Thankyou.
