 I tried to build influxdb-1.2.2.3 with GHC 8.4.1 rc1 built with
 DYNAMIC_GHC_PROGRAMS=NO. Then I got

 {{{
 [ 8 of 10] Compiling Database.InfluxDB.Query (
 src/Database/InfluxDB/Query.hs, /home/fumieval/hs/influxdb-haskell/dist-
 newstyle/build/x86_64-linux/ghc-8.4.0.20180224/influxdb-1.2.2.3/build/Database/InfluxDB/Query.p_o
 )
 cabal: Failed to build influxdb-1.2.2.3. The build process segfaulted
 (i.e.
 SIGSEGV).
 }}}

 It seems to be related to Template Haskell, as it doesn't happen if I
 remove `makeLensesWith` in `Query.hs`.
