LCOV coverage.dat file has "DA:0:0" #290

Closed thomasbao12 closed 3 weeks ago

How can a file have a zeroth line? When I look at the line numbers corresponding to "FN:14...", I see that the 14th line of a file has the function declaration.

I can reproduce this on a company codebase using bazel, but I'm not sure how to reproduce this in a separate repo which I could share.

Which platform, tools and versions are you using (lcov, gcc/llvm, etc)?

My recollection is that python's Coverage.py sometimes reports line number zero in certain scenarios.

What function is it? Perchance, a compiler-generated one? Does the rest of the data for that file look reasonable? Or is everything off-by-one?

No update/no testcase. I presume that the issue is resolved or you no longer care about it.

I will go ahead and close this issue in a couple of days - unless there is something here that needs to be addressed.
