We’ve been seeing some issues with the AirTerminalSingleDuctMixer_SimPTAC_HeatingCoilTest unit test that is here:

It fails in some cases, passes in others:

1. The test passes when built in Debug mode
2. The test passes when built in Release mode and run by itself
3. The test fails when built in Release mode and run with other unit tests

Details

The CI machine builds in Release mode and runs the unit tests individually, so that is why it isn’t appearing as a failure in the online dashboard. Building in 32 bit may result in further permutations, I haven’t tried that. What I have tried is building in Release mode on different Windows machines and one Linux VM, and this unit test fails on all of them.
