When we have a function that returns a structure with a name S, by searching the name of that structure (S), find-tag does not jump in all cases to structure's definiton, but to a function's definition that returns that structure.
I do not give here examples.
Just I wanted to make attention to you.

I think this depends on the order in which etags sees the struct and
the functions.
Anyway, when this happens, does "C-u M-." eventually finds the struct
definition?

No. It jumps to another function that returns the same structure, even there is the def. of the structure somewhere.

So you are saying that no matter how many times you press "C-u M-.",
Emacs _never_ gets to the struct definition? If so, please post the
smallest test case you can come up with that shows this problem.
Thanks.

Yes, emacs never touch that point.
I can't give example, because I do not have time to analyse the problem. Sorry.

This should not happen.
>I do not give here examples.
Just to be sure, I just tried with some examples, and I was not able to
reproduce the problem you describe. The range of possible combinations
is infinite, but the code is written so that what you describe does not
happen.

No, it should not and, as far as I can see, it does not.
Unfortunately, I don't think that we can do anything without a test case
so, if someone is able to reproduce the problem, please report a test
case.
