Could you send me off-list an example, this is, all necessary input
files that allow me to directly call xetex (and thus xdvipdfmx),
before and after the problematic commit?  I can then start to reduce
the example and contact the xdvipdfmx author, asking for further
analysis.  Or maybe you have produced such a minimum example already?
