seg fault with tsearch2 - Mailing list pgsql-general

I have Pg installed on i386 NetBSD from the NetBSD package manager. I
then installed tsearch2 and used its default installation.
I then also got the source and built from it, with debugging enabled.
Again I installed tsearch2 but my results were the same.

Created a new database, added a table with:

CREATE TABLE server_file (
    server_file_id serial NOT NULL,
    server_id integer NOT NULL,
    server_file_path text NOT NULL,
    server_file_name text NOT NULL,
    server_file_ext character varying(20),
    server_file_size integer NOT NULL,
    server_file_index tsvector,
    protocol_id integer NOT NULL
);

ALTER TABLE ONLY server_file
    ADD CONSTRAINT server_file_pkey PRIMARY KEY (server_file_id);

CREATE INDEX server_file_indexindex ON server_file USING gist
(server_file_index);

CREATE TRIGGER tsvectorupdate
    BEFORE INSERT OR UPDATE ON server_file
    FOR EACH ROW
    EXECUTE PROCEDURE tsearch2('server_file_index',
'server_file_name', 'server_file_path');

---------------Query executed:

 insert into server_file values (default,'511','/test/20-Shania
Twain-Party For Two with Billy
Curringtonmp3','mp3','323',default,'1');


---------------Output from gdb------------
