Comment (by j.waldmann):

 No. - After a clean checkout, I did
 {{{
 stack build --dependencies-only
 stack exec -- ghc -isrc -fforce-recomp -O1 -dcore-lint pure-matchbox.hs
 ./pure-matchbox -i -w Count data/z001.srs

 pure-matchbox: Oops!  Entered absent arg ww Map k (Set k1)
 }}}
 If I leave out the "-O1", or if I put "-O0", the error does not happen.
