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.

ok i find it str_get_html() from "PHP Simple HTML DOM Parser".

Now i need only save bugy html
 [2012-09-17 13:13 UTC] pajoye@php.net 
ok, as you mentioned that you pcre, I seriously hope that you are not parsing HTML using pcre. That's the best to end in a stack overflow crash with PCRE.

Use tidy or DOM instead.

Alternatively you can increase the stack size of the php.exe (using editbin.exe).
