Comment (by zudov):

 bgamari, great I've just tested it on my local machine with latest text
 and unordered-containers and the problem is gone.

 Additionally, here is a travis build report https://travis-
 ci.org/zudov/html5-entity/builds/87314690
 It still runs out of memory on ghc-7.10.1, but on ghc-7.10.2 everything is
 good.
 (compare with the previous build which used older text https://travis-
 ci.org/zudov/html5-entity/builds/69424551)

 Thanks a lot.

 I think we can close this issue now.
