MemoTrie-0.6.4 does not build with Stackage LTS 7.2

[ocramz]

While building a project containing vector-space (version unpinned), MemoTrie-0.6.4 was failing to build (but only on TravisCI).

I solved this by pinning the version of MemoTrie to the latest available (0.6.7) in the extra-deps section of stack.yaml :

extra-deps:
- MemoTrie-0.6.7
- newtype-generics-0.5

Is there an issue here to be addressed? Or maybe are you mentioning your experience to help others who encounter the same challenge?

There must be one, I just haven't had the time to investigate possible fixes

Got it. I'll keep the issue open. Thanks for raising these issues!
