You can use .o files compiled with -O, but you don't start
GHCi with -O!  Which, as I understood it, was what was puzzling Till. 

A regular, non-O GHCi is (should be) able to work fine with optimized
and non-optimized compiled code.  (I don't remember ever having any
problems with that, only with profiling and non-profiling code)

If I haven't seen further, it is by standing in the footprints of giants
