bug#20880: 25.0.50; etags fails to work

[jpff]

I used to use etags and M-. to navigate my 0.5m lines of code but for
a while now it just does not work
Debugger entered--Lisp error: (error "Autoloading failed to define function xref-find-definitions")
  autoload-do-load((autoload "xref" 1654971 t nil) xref-find-definitions)
  command-execute(xref-find-definitions)

I can load xref.elc by hand, but that makes no difference.

Running on todays sources.

Have you tried 'make bootstrap'?

bug#20880: 25.0.50; etags fails to work

[jpff]

Yes I have done make bootstrap since thus started happening, but can do it 
again
.....
done that and still see error

Arhh!! My fault.  Just seen an ancient version of xref.el lurking.  Seems 
OK now.  Many apologies -- failinf eyesight

Please provide a full recipe starting from "emacs -Q".  I cannot
reproduce the problem with today's master, FWIW.

Nice to see some part of that verbose output to be useful.
