When I try to insert an image into a blob, a segmentation
fault occurs in apache. This all worked fine in previous
versions of php that I used (4.0.4 - 4.0.6). I have recreated
this segfault on two different machines, with PHP as DSO, and
compiled-in.
Here is what seems to be the offending code in my script:
if ($ibaseconn) {
$blob_id = ibase_blob_create();
$blob_id_str = ibase_blob_close($blob_id);
if ($noDB != "1") {
ibase_query("UPDATE WN_Client_Data SET WN_Client_DataLogo=?, WN_Client_DataLogoType = '$thisType'
WHERE WN_ClientID = '$WN_ClientID'",$blob_id_str);
} else {
ibase_query("INSERT INTO WN_Client_Data (WN_ClientID, WN_Client_DataLogo, WN_Client_DataLogoType,
WN_Client_DataBriefDesc, WN_Client_DataExtDesc) VALUES ((SELECT WN_ClientID FROM WN_User WHERE
WN_UserUserName='$HTTP_COOKIE_VARS[directUser]'), ?, ,'','', '');",$blob_id_str);
}
}
