Postgesql 8 beta 5: ecpg and date type - Access violations

Hi,

There is an "access violation" caused by ecpgtypes when using date fields and ecpg.
Everything was runnig ok with dates rangin from 2000 - 2004, but this acces violation
occurs when the date with th year 1968 appears.

Looking at my program, I can see that this happens inside the SELECT into :data_admissao;
where "data_admissao" is a date type.
When I remove this field from the select, then it works.

Here is the steps to reproduce the error:

PostgreSQL 8.0.0 beta5
Windows XP Professional
MingW

Table:
CREATE TABLE funcionarios
(
id int4 NOT NULL,
nome varchar(40) NOT NULL,
data_admissao date NOT NULL,
funcao int4 NOT NULL,
CONSTRAINT funcionarios_pkey PRIMARY KEY (id)
)
WITHOUT OIDS;

Data:
INSERT INTO fpcadfun VALUES (111,'SILVA','1968-01-19',10);

Program:
class funcionario { ... };
typedef std::vector<funcionario> funcionario_type;

bool db_ler_funcionarios( funcionario_type &funcs )
{
funcs.clear();

EXEC SQL BEGIN DECLARE SECTION;
int id;
VARCHAR nome[40];
date data_admissao;
int funcao;
EXEC SQL END DECLARE SECTION;

EXEC SQL DECLARE func_cur CURSOR FOR
SELECT id, nome, data_admissao, funcao
FROM funcionarios ORDER BY id;

EXEC SQL OPEN func_cur;
EXEC SQL WHENEVER NOT FOUND DO break;

char *txt_adm;

while(true)
{
EXEC SQL FETCH NEXT FROM func_cur INTO
:id, :nome, :data_admissao, :funcao;

txt_adm = PGTYPESdate_to_asc(data_admissao);
funcionario f( id, nome.arr, txt_adm, funcao );
funcs.push_back(f);
free(txt_adm);
}
EXEC SQL CLOSE func_cur;
return true;
}

The access violation occurs at the bold line. I'm using mingw to compile this
program.

Please fell free to ask for any other question or comment about this error.

I hope that I could give my 2 cents for this incredible RDMS.
