Comment (by ttuegel):
This turns out to be a bug in Cabal, so it should be closed. Cabal doesn't
separate the HPC module interfaces for each build way. Carter has library
profiling enabled, so the library is built twice and only the profiled
module interfaces are kept. But, the test executable is compiled with
profiling disabled, so the module interface hashes don't match! See
[https://github.com/haskell/cabal/issues/2281].
