Windows build fails because of Eigen assertion YOU_MIXED_DIFFERENT_NUMERIC_TYPES__YOU_NEED_TO_USE_THE_CAST_METHOD_OF_MATRIXBASE_TO_CAST_NUMERIC_TYPES_EXPLICITLY

[ithron]

Windows build fails because Eigen complains about incompatible binary types. However, this error does not occur on any other platform.

The relevant part of the build log is listed below.
