I tried your example (your code not reproduced here) with
groff-1.18.1, without making any changes to it,  and got
no earnings, and the following output:


heading1
SN register content: >>><<<
1. heading2
SN register content: >>>1.<<<
1.1. heading3
SN register content: >>>1.1.<<<
           Table of Contents

heading1 ................................1
1. heading2 .............................1
1.1. heading3............................1

[spaces in the tab leader removed in the above]


That looks to me like what should have been produced.

Was your result different, and, if so, what is supposed to
be wrong with it?

Bestwishes,
Ted.
