Package: libeigen3-dev
Version: 3.1.0-1
Severity: normal
Tags: patch
Dear Maintainer,
the bug can be demonstrated using Hauke's example from
http://forum.kde.nl/viewtopic.php?f=74&t=98871 (see enclosed file). The call to
Spline2d::derivative<1> is an extension of Hauke's example inserted
by me. This call makes this example fail to compile:

---8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<----
This bug can be fixed by changing in
/usr/include/eigen3/unsupported/Eigen/src/Splines/SplineFwd.h the
DerivativeType from ColMajor to RowMajor (see enclosed patch for details).
With this change everything compiles fine:
