Emacs positions sometimes out of sync

[thoni56]

In some cases positions in Emacs get out of sync. It "feels" like c-xref misses to update positions.

I've not yet established a pattern for this, but it often misses a couple of lines, never columns as far as I can remember.

I'm using magit which might sometimes refresh files in the background, e.g. due to command line checkouts and the like. Maybe this is a problem... I don't know enough about the elisp code at this point to start debugging this.

A full, or even fast, update of tags seems to fix the problem.

So possible ideas:

• file updates in the background goes unnoticed
• buffer refreshs goes unnoticed
• mixed line terminations in the file screw this up (not likely since an update fixes it)
• ...

Hmm, some thing is not making sense...

When I experience this offset and move down to the real position and hit F6 (push), if the definition is in another file, then I get to the definition, but with the same offset as I had in the first file. And all the other locations are also off, except for the one I now pushed.
