🧑‍🌾 Segfaults in Homebrew CI cause test failures

[Crola1702]

Environment

• OS Version: Mac OS bigsur
• Source Garden build

Description

• Expected behavior: COMMON_TEST_simulation_features_bullet-featherstone should pass
• Actual behavior: COMMON_TEST_simulation_features_bullet-featherstone and INTEGRATION_DoublePendulum are failing due to a Segfault

Steps to reproduce

1. Run a build in gz-physics6-homebrew
2. See COMMON_TEST_simulation_features_bullet-featherstone fail.
3. If you enter the log, you can see INTEGRATION_DoublePendulum also failed due to a segfault.

Output

Reference build: https://build.osrfoundation.org/view/ign-garden/job/ignition_physics-ci-gz-physics6-homebrew-amd64/55/

The following tests FAILED:

• 105 - COMMON_TEST_simulation_features_bullet-featherstone (SEGFAULT)
• 121 - INTEGRATION_DoublePendulum (SEGFAULT) (This one is failing since build 37, but for some reason, Jenkins doesn't show it on the report)
