Coverage report is empty when running --collect-only/--report--only separately for the compiled language case about kcov

[SimonKagstrom]

One thin which might perhaps affect this is if you've built a "PIE executable", which is effectively loaded as a shared library. If you're able to recompile your application, you may try to add the -no-pie argument to the CFLAGS/CXXFLAGS and the LDFLAGS.

Sorry for the late reply!

I've tried this again, and can't seem to reproduce it here. I put your example in /tmp/a.cc, compiled to /tmp/a and ran

 src/kcov --collect-only /tmp/kcov /tmp/a
 src/kcov --report-only /tmp/kcov/ /tmp/a

and I get the same results with collect+report as without them. Ran the test on master, but I don't think anything has changed for a while which should be related to collect+report.
