Comment (by rwbarton):

 Do you still have the failing sandbox? If so can you try `cabal build
 --ghc-option=-dppr-ticks`? There are a few different kinds of ticks and
 knowing which kind it is might reveal what is special about your sandbox
 (e.g. profiling or HPC or debugging information is turned on).
