 If I have a file
 {{{#!hs
 -- Lib.hs
 module Lib where
 [d| foo = 1 |]
 }}}
 and I add `llvm-general` as a dependency, compiling with -v yields the
 attached log, followed by `segmentation fault (core dumped)`.

 Investigating with gdb, the back trace is

 {{{

 Note that without the quasi-quotation in `Lib.hs` it will compile fine,
 and without the `llvm-general` dependency it will also compile fine.
