• Actual behavior: UNIT_PointCloudPackedUtils_TEST fails with an exception during PointCloudPackedUtilsTest.MultipleFields
  • Ubuntu 20.04 armhf debbuild 5.9.0: https://build.osrfoundation.org/job/ign-msgs5-debbuilder/160/
  • Ubuntu 18.04 armhf debbuild 7.3.0: https://build.osrfoundation.org/job/ign-msgs7-debbuilder/318/

Steps to reproduce

1. Compile ign-msgs on armhf
2. Run UNIT_PointCloudPackedUtils_TEST test

For debugging purposes, I've added a patch to ign-msgs5 in a branch with extra print statements:

• https://github.com/ignition-release/ign-msgs5-release/compare/scpeters/debug_armhf_test

with this branch it has the following output:

This implicates the following code:

• https://github.com/ignition-release/ign-msgs5-release/compare/scpeters/debug_armhf_test#diff-32ac4bc36bb7f01160420c84daa497ec74ba4d7f85f42787488d21f7bb330d5bR56-R80

note that the ign-msgs8 armhf build passes since dh_auto_test was disabled in gazebo-release/gz-msgs8-release@968746c#diff-ca57fdb967ecdb509f9c30a24cc95d5c076a2729573cefab26fe003088f5016c

@j-rivero I believe this is blocking builds of ign-msgs5 on armhf and by proxy builds of ign-transport8. How do you recommend that we address this?

msgs5

• focal armhf https://build.osrfoundation.org/job/ign-msgs5-debbuilder/236/
• bionic armhf https://build.osrfoundation.org/job/ign-msgs5-debbuilder/231/

transport8

• focal armhf https://build.osrfoundation.org/job/ign-transport8-debbuilder/133/
• bionic armhf https://build.osrfoundation.org/job/ign-transport8-debbuilder/128/
