Gcovr output coverage rate does not match codecov reports rate

[msclock]

I have tested it with output format xml or lcov. All result turns out console coverage rate 100% does not matche codecov report rates(67.74%). Here is my codecov report result:

Is there anything I have missed to get the matched results😕

This is my gcovr usage(coverage rate is 100%):

[5/6] cd /home/runner/work/ss-cpp/ss-cpp/out/build/x64-linux-gcc && /home/runner/cmake/cmake-3.28.1-linux-x86_64/bin/cmake -E rm -f /home/runner/work/ss-cpp/ss-cpp/out/build/x64-linux-gcc/code_coverage/coverage.xml && /opt/pipx_bin/gcovr --print-summary --xml-pretty --root /home/runner/work/ss-cpp/ss-cpp --exclude-noncode-lines --output /home/runner/work/ss-cpp/ss-cpp/out/build/x64-linux-gcc/code_coverage/coverage.xml --gcov-executable=/usr/bin/gcov --filter /home/runner/work/ss-cpp/ss-cpp/src --exclude out/build/x64-linux-gcc --exclude out/build/x64-linux-gcc/vcpkg_installed --exclude vcpkg --exclude ../../../../../usr --exclude ../../../../../opt --exclude ../../../../../opt/local

Instead of the coverage.xml the upload script executes gcov on it's own (see line 46) and uses this result.

I remeber I have tested before and now I test it again with a non-existance plugin pycoverage here but still got the same mismatched result.

In the link gcovr and codecov both report 100% line coverage. Where exact is the difference?

in recent result seems it is caused by the branches coverage and I need to do more verification.
