[Crola1702]

Bug report

Required Info:

• Operating System:
  • Ubuntu Noble
• Installation type:
  • Source
• Version or commit hash:
  • Rolling, Jazzy
• DDS implementation:
  • Cyclonedds
• Client library (if applicable):
  • rclpy

Steps to reproduce issue

1. Run a build in Rolling cyclonedds or Jazzy cyclonedds
2. See test regressions appear

Additional information

Reference build:

• https://build.ros2.org/view/Rci/job/Rci__nightly-cyclonedds_ubuntu_noble_amd64/60/#showFailuresLink
• https://build.ros2.org/view/Jci/job/Jci__nightly-cyclonedds_ubuntu_noble_amd64/23/#showFailuresLink

Test regressions:

• projectroot.test_guard_condition
• rclpy.rclpy.test.test_guard_condition.TestGuardCondition.test_double_trigger
• rclpy.rclpy.test.test_guard_condition.TestGuardCondition.test_trigger

Log output:

projectroot.test_guard_condition (and TestGuardCondition.test_double_trigger and TestGuardCondition.test_trigger)

This is a consistent issue for Rolling and Jazzy CycloneDDS

[Crola1702]

This is still a consistent issue in nightly-cyclonedds jobs (Rci, Jci)
