GHC -fhpc code coverage on Windows 10

I'm trying to check code coverage for my tasty unit tests. I found a way to do it in the GHC docs user guide for hpc. The problem is that ghc -fhpc Myfile.hs doesn't generate a .hpc subdirectory or any .tix file, as the documentation claims it to do. Subsequently, I cannot run hpc report.

What am I missing? Does this not work on Windows?

Apparently, removing all *.hi and *.o files, forcing the compiler to recompile, worked. I really think the compiler should've noticed the flag, and that some files were missing.
