Flaky Windows test regressions: Access Violation

[Crola1702]

Migrated from https://github.com/osrf/buildfarmer/issues/321 on July 1st 202

In build log, we can see an error like this:

<path> Windows fatal exception: access violation

The list of paths we've seen is:

• ..\..\src\ros2\rosbag2\rosbag2_py\test\test_sequential_reader.py (Windows Debug and Release)
• ..\..\src\ros2\rosbag2\rosbag2_py\test\test_sequential_reader_multiple_files.py (Windows Debug and Release)
• ..\..\src\ros2\rosbag2\rosbag2_py\test\test_sequential_writer.py (Windows Debug and Release)
• ..\..\src\ros2\rosbag2\rosbag2_py\test\test_convert.py(Windows Debug and Release)

It does not affect build success or failure (as far as we know).

Conclusions from this output:

1. The issue is consistent (despite it show 86% of the times, in reality, the missing 14% and disconnected agent failures)
2. Most regressions are happening for rosbag2_py package, but there are also some few rclpy ones. This means it's probably a python related issue.

Reproducing failure:

Test using last FastDDS stable version:

In the reproduced failure we can see:

00:59:24.271 test\examples\check_node_launch_test.py --- stderr: launch_testing_ros
00:59:28.208 Windows fatal exception: access violation

The most probable option is that eProsima/Fast-DDS#4151 make the Access Violation error consistent.

Thanks for doing some additional work here! That said, I don't think I agree with your conclusion. It looks to me like eProsima/Fast-DDS#4151 works just fine, and it is instead that eProsima/Fast-DDS@eae72fd caused the problem. I'll report a bug to upstream Fast-DDS.

[Crola1702]

Thanks for checking it! You're right, the newest change was eae72fd and it broke our builds!

[Crola1702]

@clalancette, just checking, did you report the issue to FastDDS?

[clalancette]

Sorry, I forgot. I've done it now: eProsima/Fast-DDS#4230
