In /var/log/apache/error_log :

/root/php4-STABLE-200307102330/main/main.c(1718) : Bailed out without a bailout address!

I dont?t know if is related.

I find where is the problem.
In code :

$db=ocilogon("user","pass","db");
$curs = OCINewCursor($db);

$cod_empresa = 15;
$codAcervo = 154173;

$stmt = OCIParse($db,"begin sp_per_consulta_obra($cod_empresa ,$codAcervo,:reg_sql);end;");
ocibindbyname($stmt,":reg_sql",&$curs,-1,OCI_B_CURSOR);
ociexecute($stmt);
ociexecute($curs);
if(OCIFetchInto($curs,&$reg_sql,OCI_ASSOC))
{
	echo "ok";
}
else 
{ 
	echo "error";
}

If i comment the line : $curs = OCINewCursor($db); 
the page is found. The error seems to be in OCINewCursor.
My php version is php4-STABLE-200307142330, Oracle Client is 9.2, apache is apache-2.0.45-28790U90_2cl.
Thanks

Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same. Because of this, we hope you add your comments
to the existing bug instead.

Thank you for your interest in PHP.
