extension_loaded() causes Apache to lock up tight!

Environment: Win XP, Wamp5 (Apache 2.0.53, PHP 5.2.0)

As it stands, win32ps.dll is not loaded, thus,
extension_loade d('win32ps') should return false:

Array
(
[0] =bcmath
[1] =calendar
[2] =com_dotnet
[3] =ctype
[4] =session
[5] =filter
[6] =ftp
[7] =hash
[8] =iconv
[9] =json
[10] =odbc
[11] =pcre
[12] =Reflection
[13] =date
[14] =libxml
[15] =standard
[16] =tokenizer
[17] =zlib
[18] =SimpleXML
[19] =dom
[20] =SPL
[21] =wddx
[22] =xml
[23] =xmlreader
[24] =xmlwriter
[25] =apache2handler
[26] =mbstring
[27] =gd
[28] =mysql
[29] =mysqli
[30] =PDO
[31] =pdo_sqlite
[32] =SQLite
)

But instead Apache locks up into an infinite loop, producing no Apache
errors, no PHP errors, no output, nothing, just sits there trying to
load the phge without ever timing out or even producing 100% CPU
memory loss!

Have you ever seen this before with extension_loade d(), a bug or what
is really going on?

Thanx
