ci: coverage fails on debian:testing runners

[dgreatwood]

gcc produces this error, during the "coverage" phase:

geninfo: ERROR: (unused) 'exclude' pattern '/github/home/.cache/*' is unused.
Excluding file '/usr/include/c++/13/bits/shared_ptr.h'
	(use "geninfo --ignore-errors unused ..." to bypass this error)

While clang produces this error:

geninfo cmd: '/usr/bin/geninfo . --output-filename coverage.info --gcov-tool /github/home/.local/bin/cov.sh --exclude /usr/* --exclude /github/home/.cache/* --exclude */tests/* --exclude */subprojects/*'
Found LLVM gcov version 16.0.6, which emulates gcov version 4.2.0
geninfo: ERROR: Your toolchain version is too old and is no longer supported by lcov.  Please upgrade - or use an older lcov release.

There are a couple of warnings as well, which look unimportant as far as I can see.

Could someone (@Tachi107 ?) fix these errors? Otherwise I guess we could remove debian:testing from the linux.yaml matrix.

Thanks!

Hi Duncan, yeah, I'm aware of those issues and I have attempted fixing them in #1188, but it's far from trivial. Lcov 2.0 introduced some changes that make it incompatible with our CI pipeline, and trying to use gcov directly seemingly doesn't work with Codecov even when following the official documentation. I'm a bit lost and I'm just waiting for Codecov to publish a working solution ¯\_(ツ)_/¯

Makes sense. Leaving this in your hands, but LMK if you’d like me to try something out. Thanks!

I've disabled the Coverage step for debian:testing runners in aa2a9f2, but I'll keep this issue open to track the actual issue.
