Steps to reproduce issue

Run test_rclcpp tests on ARM64 or macOS and you have a chance of the test timing out rather than completing. Here's an example build where I reached into ament_cppcheck and bumped the timeout up to 240. The test completed in 131s.

Expected behavior

cppcheck runs to completion

Actual behavior

cppcheck run times out before completion generating no test result output.
