my counter usually gets incremented by 1, when I use \stepcounter{mycounter}

But surprisingly, it gets incremented by 2, when I use it together with listings:

    firstline=1, lastline=10, firstnumber=1

What's wrong about that?
And how can I achieve the counter to be incremented by one?

I cannot see it with your code, it is incremented by 1! Create a complete example which shows your behaviour! – Herbert Sep 21 '11 at 17:25

I bet listings measures width of the title by typestting it into a box which is then discarded, before typesetting it for real, or something similar. Then you get the counter incremented twice.

Thank you for your reply. It sounds like a good idea. Do you know a way around this behaviour? – user8006 Sep 21 '11 at 17:10
@Timo: Perhaps put the \stepcounter before the listing, rather than in the title? It has only one title and, logically, the numbering belongs to the listing and not to the title itself. – Ryan Reich Sep 21 '11 at 17:18
If you use it repeatedly, wrap it in a macro like \def\myListing#1{\stepcounter{mycounter}\lstinputlisting[title={\arabic{mycount‌​er}},firstline=1,lastline=10,firstnumber=1]{#1}} and then use \myListing{mytextfile.txt}. – eudoxos Sep 21 '11 at 17:54
