...れなくなってしまう ⇒ れなってしまう？

In this wikipedia article there is a line: ・・・時平はそれが気になって居ても立ってもいられなってしまう。Now i wonder whether it is a misprint or an acceptable contraction of 居ても立ってもいられなくなってしまう?

It's just a typo of いられなくなってしまう.

Thank you Toritoribe.
I've created a wikipedia account just to make a revision. Now it reads いられなくなってしまう　as it is supposed to.
Actually this typo made me consider starting a thread called "typo or not?". Will do so next time.
