I reprofuced the crash with Apache2 using ApacheMonitor.exe
The problem is not releated to socket, but to persistent resources.
Under Apache2/win32 PHP doesn't free resources on thread exit and frees
them on apache shutdown using tsrm_shutdown(). But tsrm_shutdown() is
called after zend_shutdown(), when "HashTable list_destructors" is
already destoyed. As result we got crash trying to access
"list_destructors" from "plist_entry_destructor".

Dmitry, can you take a look?

All my php dlls are isolated in a directory extracted from the zip
distribution. The trace debug log shows all dlls loaded from the
appropriate locations.
Loaded symbols for 'C:\apache\php\php5apache2.dll'
Loaded symbols for 'C:\apache\php\php5ts.dll'
Loaded 'C:\apache\php\ext\php_sockets.dll', no matching symbolic
information found.
I've tested this with all of zend extensions disabled (sometimes i use
xdebug) as well as all extensions disabled with the exception of
php_sockets.dll.

1) Have you installed PHP cleanly? Make sure you delete EVERY php
related DLL, etc. before installing new versions.
2) What extensions do you load in your php.ini?
3) What zend extensions do you load in your php.ini?
