Unfortunately, -debug seems to conflict with -threaded:

  ghc --make -threaded -debug -O -Wall [...] -o postmaster tutorial.lhs [...]
  Chasing modules from: tutorial.lhs
  Compiling Main             ( tutorial.lhs, .objs/Main.o )
  Linking ...
  /usr/lib/gcc-lib/i686-pc-linux-gnu/bin/ld: cannot find -lHSrts_thr_debug
  collect2: ld returned 1 exit status

Would compiling with -debug and without -threaded still
