This has been reported on Gentoo: https://bugs.gentoo.org/397643
The relevant commit to the xine-lib repository is
http://anonscm.debian.org/hg/xine-lib/xine-lib-1.2/diff/806b590a4d38/src/xine-engine/video_out.h
This change addresses the issue. I'm sending the full modified file as
an attachment. It is based on the 3.0.1 release of OSG. I'll also paste
a diff below. You will find a colorized view in the Gentoo bugzilla.
The xine-lib API changed in the following way: the identifier and
description members are now "const char*" strings instead of "char*
(*)(video_driver_class_t*)" getter function. As the functions in the osg
plugin will always simply return a string literal, without accessing
their argument, it is safe to simply call them with a NULL argument and
use the returned string. This makes it easy to support both API
versions. When you drop support for older xine one day, you might want
to move the string literals to the assignment, getting rid of the
functions in the process.
The modified code compiles for me. I'm not sure how to test it, as I've
only got OSG around in order to build (and hopefully one day even use)
Flightgear.
I'm assigning my copyright in this change to the osg project leads.

parameter in osg::Image. To support this Image::setData(..) now has a new optional rowLength parameter which
defaults to 0, which provides the original behaviour, Image::setRowLength(int) and int Image::getRowLength() are also provided.
With the introduction of RowLength support in osg::Image it is now possible to create a sub image where
the t size of the image are smaller than the row length, useful for when you have a large image on the CPU
and which to use a small portion of it on the GPU. However, when these sub images are created the data
within the image is no longer contiguous so data access can no longer assume that all the data is in
one block. The new method Image::isDataContiguous() enables the user to check whether the data is contiguous,
and if not one can either access the data row by row using Image::data(column,row,image) accessor, or use the
new Image::DataIterator for stepping through each block on memory assocatied with the image.
To support the possibility of non contiguous osg::Image usage of image objects has had to be updated to
check DataContiguous and handle the case or use access via the DataIerator or by row by row. To achieve
this a relatively large number of files has had to be modified, in particular the texture classes and
image plugins that doing writing.
then reload a video and finally delete the second XineStreamImage.
In src/osgPlugins/xine/video_out_rgb.c, many code is ASM code, and 'clear()' function is one of them.
If OSG is compiled without the flag COMPILE_ASSEMBLY (default behaviours) the clear() function is an empty
function and allocated memory is never initialized to 0. So a structure which contain pointer haven't its pointer set to NULL.
And when we need to delete this pointer, all go bad.

allows geometry setup code to flip the t tex coord to render the movie the correct way up.
