Re: BUG #17706: ALTER TYPE leads to crash

With PL/pgSQL:

create type foo as (a int, b int);

create function bar() returns record as $$
declare
        r foo := row(123, 2^30);
begin
        alter type foo alter attribute b type text;
        return r;
end;
$$ language plpgsql;

postgres=# select bar();
server closed the connection unexpectedly
  This probably means the server terminated abnormally
  before or while processing the request.

LOG:  server process (PID 394076) was terminated by signal 11: Segmentation
fault

(Here 2^30 is interpreted as a string length.)
