Looking in TeX: The Program, I see that this "*" comes from the  
print_spec procedure in module 178, and it looks like it can only  
appear if the glue specification has somehow become corrupted. This  
supports my feeling that we're seeing a XeTeX bug that shows up under  
conditions of extreme memory and/or font resource usage.
