Oh, yes you do:
+ name 0x01b22100 "threads"
- functions 0x01b23010
+ fname 0x01b22188 "thread_start"
This is PECL/threads, which has never been officially released.

1] Request php page from browser.
2] wait for sometime for any output.
3] Open TaskList.
4] Right click Php.exe and Debug.
5] In MSVC, Break the execution.
Above are the steps to get the output as below in the call stack.

I've not installed any of PELC options.
------------------------------------------------------------------------
[2006-11-16 12:06:30] jitudavda at hotmail dot com
Code is compiled with the following options.
cscript /nologo configure.js --enable-debug-pack
--with-php-build=D:\php_build\ --without-libxml
I started the debug of php.exe in MSVC. Argument given was a file with
content "<?php phpinfo();"
