reproducible database crash with simple sql command on postgres 8.3.1

hi all,

first i create a table
create table regions (id integer, name varchar);

then i want to set a default value for a column, e.g.
alter table regions alter column name set default 'bavaria';

at this point crashes the database with the message

PANIK: ERROR_STACK_SIZE exceeded

the rest of the message is unfortunately in german then i have to
restart the postgres-service manually this error is very easy
reproducible at my environment

is this a problem of my installation or can anybody reproduce this error
at his environment

thanks and greetings from munich
christian

p.s. os windows xp, sp2
postgres 8.3.1, visual c++, build 1400
