[ros-users] Data is not aligned assertion fails... (SACSegme…

Hi everyone,

was using the PCL to detect the dominant plane from a point cloud, similar
to what is done in package tabletop_object_detector using SACSegmentation or
SACSegmentationFromNormals and one assertion fails:

/home/aa/ros/stacks/point_cloud_perception/eigen3/include/Eigen/src/Core/MapBase.h:192:
void Eigen::MapBase<Derived>::checkSanity() const [with Derived =
Eigen::Map<Eigen::Matrix<float, 4, 1, 0, 4, 1>, 1, Eigen::Stride<0, 0> >]:
Assertion `(!(ei_traits<Derived>::Flags&AlignedBit) ||
((size_t(m_data)&0xf)==0)) && "data is not aligned"' failed.

Tried the example from:
http://www.ros.org/wiki/pcl/Tutorials/Planar%20model%20segmentation

and the error persists but it does not occur always, just every now and then
:S I am testing on a 32-Bit Ubuntu operating system.

Any idea? I would really appreciate it.

Thanks in advance.
Aitor
