simple function crashes my postmaster - Mailing list pgsql-sql

Hi,

there is a mystic problem with a simple C function which creates a table. 
I minimized the code to reproduce the error. It crashes on two different 
Linux systems (SuSE) and with pg 7.0/7.1. I found that the crash occurrs 
as soon as I use a SERIAL type in the table creation command.

Please help,

thank you,

Markus

Here is the C function:

bool crash ()
{if (SPI_connect () < 0) return (false);
SPI_exec ("CREATE TABLE atl (idx SERIAL)",0);
SPI_finish ();
return (true);
}

Here is the SQL code:

CREATE FUNCTION    crash() RETURNS BOOL AS '/usr/lib/mycode.so' LANGUAGE 'C';
SELECT crash();

And this is the backend's log:
