> When coverage and dev-mode are enabled with DONT_OPTIMIZE, it causes build failure.  The double compilation does a 'shadow' build of each file with output to /dev/null.  Unfortunately when coverage is enabled, GCC tries writing to /dev/null.gcno (at least some versions do).  This prevents the build from proceeding.
> The simple fix is to simply prevent COMPILE_DOUBLE when coverage is enabled, that is what I'm proposing here.  The other option would be to use a real output location instead of /dev/null, delete the file immediately after building.  I'm not sure that is needed, so I've proposed the simpler fix.
