Ah, sorry :)  Just tested on 7.4 and it works fine (as expected).

qq=# select version();
                                version
------------------------------------------------------------------------
 PostgreSQL 7.4.1 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.2.2
(1 row)
qq=# SELECT txt2txtidx('Hello A-1');
    txt2txtidx
-------------------
 '1' 'a-1' 'hello'

Also, I run test on 7.3.3

qq=# select version();
                            version
---------------------------------------------------------------
 PostgreSQL 7.3.3 on i686-pc-linux-gnu, compiled by GCC 2.95.3
(1 row)

qq=# SELECT txt2txtidx('Hello A-1');
    txt2txtidx
-------------------
 '1' 'a-1' 'hello'
(1 row)

Everything  is ok.

I see your version of postgresql is outdated (you may upgrade at least
to 7.3.5 !) and most suspicious is the version of your compiler 2.96 !
I don't remember 2.96 was officially released ! I'd recommend to think twice
about your compiler. Don't know if postgresql supports unoffical releases.
