I'm currently facing an issue with generating .gcda files for coverage data of a static library. I can get coverage data for most files, but not all.
I'll refer to the object file with the missing coverage data as X.
Some things to note:
- I have compiled the library and test executable with the appropriate flags.
- The .gcno files are generated for all objects, including X.
- The .gcda files are generated for MOST objects, excepting X.
- The symbol dump of X's object file has the gcov symbols present in its disassembly.
When running a test that uses X, .gcda files are generated for other files, just not X.
What could be happening that prevents a single .gcda file from being generated?
