[Gmsh] Negative Jacobians in 2nd Order Mesh

I have a geometry for which 1st order tetrahedral meshing works fine (with
no negative jacobians). For the 2nd order case, I get a few negative
jacobians. This problem does not go away even when I try to regularize the
mesh or reduce mesh sizes in certain regions with small geometric features.

Does someone have a suggestion?

Best regards,
