Explanation
The title "RFC: Code cov exclude debug []" is partially related to the changeset. The change adds GCOVR_EXCL_START/GCOVR_EXCL_STOP markers around debug-only code and excludes generated IFC and Unicode data files from Codecov in .github/codecov.yml. The title names the debug-code exclusion, which is the main part of the change. It omits the generated-file exclusion. The trailing "[]" and the "RFC:" prefix add noise, and "Code cov" is an unusual spelling of Codecov.

Remove the exclusion markers from the documentation comment.
The #if DEBUG and #define dbprint text is inside an existing block comment. The added /* GCOVR_EXCL_START */ marker creates a nested comment. The stop marker then closes the surrounding comment. The compiler parses the example text as source code, which causes the unmatched #endif and prevents all builds from completing.
Remove both markers. If the real dbprint definition needs exclusion, annotate that definition outside the documentation comment.
Proposed fix
#if DEBUG
- /* GCOVR_EXCL_START */
#define dbprint printf
- /* GCOVR_EXCL_STOP */

Source: Pipeline failures
A lot of the code coverage issues reported are in helper debug functions; including these makes our numbers look a fair bit worse for code that's realistically not part of the production build.
While this is a mechanical change, this is also a fairly invasive change, so I want to get feedback on it before proceeding with a merge.
