PHP Bug Type: Performance problem
Bug description: Perl Interpreter Problem
Description:
------------
Our project uses the Perl Interpreter to access a Perl package
that returns an array reference that will be displayed by a PHP class.
The problem is that the Perl Interpreter attempts to free non-existent
shared strings during global destruction.
This dumps over 12,000 lines of text into the Apache log and
impacts performance.
Reproduce code:
---------------
$perl = new Perl();
try {
$perl->eval('use lib "includes/modules/";');
$perl->eval('use Assessment;');
$dAr=$perl->{"Assessment::report"}($_POST);
}
catch (PerlException $exception) {
echo "Perl Error: " . $exception->getMessage();
}
Assessment is a Perl package that queries a DB2 database and
returns data that is displayed in the browser.
Expected result:
----------------
The apache log file without all the error messages
Actual result:
--------------
Over 12,000 lines of text in the apache log file that look like this:
Attempt to free non-existent shared string 'exe_ext' during global
destruction.
