Description:
------------
I tried to parse large html file - 300kb with preg_match_all. The data needed was between <!-- reg:Region_name --> / <!-- end-reg --> elements so i did this pattern #reg:(.+) -->(.+)<!-- end-reg -->#. This was working fine on old version of php (4.4) but what a surprise when upgraded to 5.2.5 ?!? It did not found any matches when the text between the reg and end-reg markers is too large. I tried moving the end-reg marker close to the reg: marker to cover smaller area of html code and it worked for enough small areas. I experimented and moved the end-reg 1 char away from the reg: and it did not returned any match.

So i think this is bug and depends of the size of the text i want to match.
