Out of memory

Hi,
I'm not sure if you know this problem.

Create an empty function with 26 parameters:

create function test (INTEGER,TEXT,TEXT,TEXT,CHAR(16),CHAR(11),
BOOLEAN,BOOLEAN,BOOLEAN,BOOLEAN,BOOLEAN,BOOLEAN,
BOOLEAN,BOOLEAN,BOOLEAN,CHAR(2),TEXT,TEXT,TEXT,TEXT,
CHAR(5),TEXT,TEXT,TEXT,TEXT,TEXT )
returns integer as '
declare
begin
return 0;
end;' language 'plpgsql';

Call it mistyping the boolean parameters:

select test
(1,'a','a','a','a','a',1,1,1,1,1,1,1,1,1,'a','a','a','a','a','a','a','a','a','a','a');

Then the system crashes.

In /var/log/messages I found:

[...]
