Description:
------------
The size of the resulting string of the search using ereg & eregi seems to be limited.

Reproduce code:
---------------
$GrabData = ereg("$GrabStart(.*)$GrabEnd", $RetrieveFile, $DataPrint);

echo $DataPrint;

Where $GrabStart & $GrabEnd are items chosen within the $RetrieveFile



Expected result:
----------------
I was expecting whatever portion of $RetrieveFile to be output as determined by $GrabStart & $GrabEnd

Actual result:
--------------
It worked to a certain extent until $GrabStart & $GrabEnd where more than a certain distance apart in the file then it failed. 

ereg returned a value rather than TRUE or FALSE. The max value it returned before failure seemed to be around 8969
which corresponds to the amount of data returned which was about 8,920 bytes

Thank you for this bug report. To properly diagnose the problem, we

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 possible, make the script source available online and provide
an URL to it here. Try avoid embedding huge scripts into the report.
