Backend crash with tsearch

I'm evaluating tsearch contrib module, and i get a backend crash when
i'm about to use a tsearch function.

When i issue
update things set nidx=txt2txtidx(productname),
didx=txt2txtidx(longdescription);

The backend dies in a segfault.
The system is redhat 7.3 dual athlon w/ 1GB memory.
Postgresql is compiled with -march=athlon -O3.
initdb -E LATIN1

I have a huge shared buffer count (65536).

I'll reinstall tsearch and try again soon.
Is it necesary to install OpenFTS contrib aswell, or do i get away with
only installing tsearch?
Now i do both...
