Comment (by RyanGlScott):

 As far as the original ticket goes, I'm stumped. I tried to construct a
 minimal Template Haskell program which should eat up memory by causing a
 space leak:

 {{{#!hs
 {-# LANGUAGE TemplateHaskell #-}
 module Bug where

 $(let f :: Int -> a
       f x = f (x + 1)
   in f 0)
 }}}

 I tried compiling this on GHC 8.2.2 with and without `-O2`, but despite it
 using all of my 8GB of memory available, this didn't trigger a segfault.
