OK, replacing line 44 of Eigen/src/Core/functors/UnaryFunctors.h with:
EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE const result_type operator() (const Scalar& a) const { using std::fabs; return fabs(a); }
To the dev team: is this to be considered as a fix and maybe pushed to the main repo?

No, that would break some other types. Please try to investigate why it isn't working with 'abs' for you.
