i have been suffering from this, too, but recompiling everything from 
scratch did not fix this. Searching further, i found that the attribute 
__DRI_ATTRIB_YINVERTED has been enabled in the attribute offset list 
used to compare with attributes in the DRIconfig struct, although the 
needed infrastructure for that attribute is not in place, leading to 
failure in all compares.
