This may be related to the issues reported in #1379 (with preliminary findings https://github.com/Cantera/cantera/issues/1379#issuecomment-1418240342)

[speth]

Of course this is the same as #1379. It's just two slightly different ways of compiling the same program. I don't think we need two issues to track the problem.

[ischoegl]

Yup. Got there using a different (more standard) approach. As your explanation in #1379 already points to the core issue, I am closing this one here.
