The record of coverage is cumulative across multiple runs. Is it possible that you did not remove an old .tix file before running the tests?
Thanks for your reply I was beginning to worry I might be the only person trying to use this. I've done a bit of investigation and it seems there are at least two problems: 1. I have literate haskell files (.lhs). 2. Even if I run them through the pre-processor (ghc -E) they still don't work but if I manually remove these lines (which seem to get inserted by the pre-processor) {-# LINE 1 "ASNTYPE.lhs" #-} #line 1 "ASNTYPE.lhs" then it does actually work. It looks like a bug to me. I guess I should report it on the ghc trac. I still have a problem with another project which doesn't use literate haskell but does require the use of -cpp and has got #ifdef's. I haven't got to the bottom of it yet but I'm suspicious that lines starting with # cause hpc to misbehave. It's strange that hpc should behave like this as I would have thought it wouldn't care about hs / lhs and # as ghc would have done some of its standard processing before hpc got engaged.
