For code coverage (gcov) to work, I need to compile with the following compiler switches -fprofile-arcs and -ftest-coverage (or --coverage).
Do you mean that ccache fails with these options (i.e. a bug) or that it just gives no speedup (i.e. a missing feature)?
Since ccache 3.0 correctly handles the mentioned flags (though without any speed up), I'm closing the bug.
Please reopen the bug if it was meant as a feature request to get ccache to speed up builds with the flags.
Sorry, but... can I ask why?

What do you mean?
