I'm facing this problem only when I compiled the code using -O2 Flag.

I tried the following,

* Compiled with -O1 Flag (7.4.1), It compiled fine

* Compiled with ghc-7.0.4 with -O2, it's getting compiled successfully but with the Warning,

[Module that is getting stuck is using heavy quasiquotation]

Env:

OS: Ubuntu 12.04 [x86_64]

GHC: 7.4.1

Is this a bug?

Anything else should I need to try?
