I compiled ros2 rolling with the mixin coverage-gcc but I'm not able to reproduce this error locally

• coverage-gcc mixin

@Crola1702 @mjcarroll any ideas about how to reproduce this locally ?

[Blast545]

I don't think this is the most straightforward way to reproduce it, but I just installed the mixins and ran the same build and test commands that are run in CI, and was able to reproduce the error.

Those are the commands that I used, in case it helps:

colcon mixin add default https://raw.githubusercontent.com/colcon/colcon-mixin-repository/master/index.yaml
colcon mixin update default

[Blast545]

The errors is happening in rosidl_typesupport_introspection_tests, so I imagine this should suffice:

colcon mixin add default https://raw.githubusercontent.com/colcon/colcon-mixin-repository/master/index.yaml
colcon mixin update default

colcon build --base-paths "src" --build-base "build" --install-base "install" --event-handlers console_cohesion+ console_package_list+ --cmake-args -DBUILD_TESTING=ON --no-warn-unused-cli -DCMAKE_BUILD_TYPE=Debug -DINSTALL_EXAMPLES=OFF -DSECURITY=ON -DAPPEND_PROJECT_NAME_TO_INCLUDEDIR=ON --packages-up-to rosidl_typesupport_introspection_tests --ament-cmake-args -DCMAKE_CXX_FLAGS="${CMAKE_CXX_FLAGS} --coverage" -DCMAKE_C_FLAGS="${CMAKE_C_FLAGS} --coverage"

colcon test --base-paths "src" --build-base "build" --install-base "install" --pytest-with-coverage --event-handlers console_cohesion+ --retest-until-pass 2 --ctest-args -LE xfail --pytest-args -m "not xfail" --packages-up-to rosidl_typesupport_introspection_tests
