 For example:


 {{{
 % cat t.hs
 f x = x * 20
 main = print (f 20)
 % cat pp
 #!/bin/sh
 cp $2 $3
 % ghc -fhpc -F -pgmF./pp t.hs
 [1 of 1] Compiling Main             ( t.hs, t.o )
 Linking t ...
 % cat .hpc/Main.mix
 Mix "t.hs" 1308170257 1934109072 1 []
 }}}

 If I omit pgmF, then I get proper Boxes in the .mix file.  When I run over
 a large code base, some scattered expressions get Boxes, but the majority
 don't.

 I think this started showing up with ghc 7.
