After some experiments the proposed patch might not work at all.

compilation-auto-jump timer is fired by the font-locking engine. By my
observation it is possible that compilation-finish-functions (from a
process sentinel) are executed before font-locking even by inserting

  (compilation--ensure-parse (point-max))

in ggtags-global-handle-exit.

Do you see any anomaly in the observation?

The hack that is now in ggtags.el may not work either. None of the
people that reported https://github.com/leoliu/ggtags/issues/89 have
confirmed the fix. And I personally don't know how to reproduce it.
