I will try later with the latest svn.

I have an older version (8504) and your posted command line for 
stereomatch works on Linux here:
The top right is white, but the top left shows the disparity image.

osgmultiplerendertargets without params should display a light yellow 

I also post my warnings, they are similar to yours, you do not need a 
specific enable for sampler2DRect, OSG does this.

It seems something is up with FBO and multiple targets. Can you check if 
osgprerender works properly?
