Error message is generated saying "The instruction at "0x78003abf" referenced at "0x00bc8000". The memory could not be "read".

Because it seems that the problem is memory leak I am providing a part of the php code where I am accumulating a large string width data (separated with "|") which I am going to pass later on javascript for further manipultion. 

The number of records passed by the SQL query is about 900.

While developing the script, to avoid the error I raised the memory limit consumed by script (in php.ini) first to 16M, later 32Mb, now it is 64M.

The strange thing for me is that after I raised to 16M, the error stopped, than sudenly apperred again; when I put it on 64M it stopped again, and now it comes back again without realy modifying this part of the script!


// the code
$sql = "select GROUPID, SUBGROUPID, MATERIALID, DESCRIPTIONEN, DESCRIPTIONBG, COSTPRICE from MATERIALS";
  $h = ibase_query($sql);
  while($row = ibase_fetch_object($h)) {
  if ($lang_selected == "en") {
  $dsc = $row->DESCRIPTIONEN;
  if ($dsc == "") { $dsc = $row->DESCRIPTIONBG; }
  } else {
  $dsc = $row->DESCRIPTIONBG;
  if ($dsc == "") { $dsc = $row->DESCRIPTIONEN; }
  }

$mats .= trim($row->SUBGROUPID)."|".trim($row->MATERIALID)."|".trim($dsc)."|".$row->COSTPRICE."|";
$qq++;
       }
ibase_free_result($h);
