Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.

Description:
------------
I run some code 5 million itteration yesterday, today I change my
string building to use single quotes and the dot operator. That version
was able to do aprox 25k itterations then the script died due memory
leak.
Reproduce code:
---------------
# Makign a string like this leaks NOT memory
# $lInsert = "Insert into {$this->mTable}
(datetime,entity_id,entity_type,domain,country,location,raws,uniques)"
.
# " values
('{$this->getDateTime()}',{$this->getEntityId()},{$this->getEntityType()},{$this->getDomain()},"
.
#
"{$this->getCountry()},{$this->getLocation()},{$this->getRaws()},{$this->getUniques()});";
# Making a string liek this leaks memory when doign execute
$lInsert = 'Insert into '.$this->mTable.'
(datetime,entity_id,entity_type,domain,country,location,raws,uniques)'
.
' values
("'.$this->getDateTime().'",'.$this->getEntityId().','.$this->getEntityType().','.$this->getDomain().','
.$this->getCountry().','.$this->getLocation().','.$this->getRaws().','.$this->getUniques().');';
# $lInsert = "Insert into {$this->mTable}
(datetime,entity_id,entity_type,domain,country,location,raws,uniques)"
.
# " values
('{$lTimeStamp}',{$lEntityId},{$lEntityType},{$lDomain},{$lCountry},{$lLocation},{$lRaws},{$lUniques})";
#
print memory_get_usage()."\n";
$lStatement =& $this->mDbh->prepare($lInsert);
if (MDB2::isError($lStatement)){
error_log($lStatement->getMessage().';query:'.$lInsert.'
'.$lStatement->userinfo);
$lResult = false;
} else {
$lResult =& $lStatement->execute();
$lStatement->free();
}
Expected result:
----------------
See code comments
Actual result:
