Clang vs. GCC – code coverage checking

This sounds a bit dangerous. Code coverage works on code, not on data, so if you're testing something like:

    // globals
    rules_t rules[] = {{1, OK}, {2, FAIL}, {3, THERMONUCLEAR_WAR}};

It sounds like you could change rules 1 and 2 to THERMONUCLEAR_WAR as well and none of the tests would rerun. Is that right?

You might do something like this for local development, keeping things fast with some confidence you're not grossly breaking things. But you run the full suite through CI.
