Description:
------------
My configuration: Windows XP, PHP 5.2.5. cURL extension periodically is crashing at offset 00018ed8. I use both curl_* and curl_multi_*. Also, cURL extension has memory leaks. After about 30 minutes of intensive use of cURL functions, i get memory usage over 1G.

Reproduce code:
---------------
i create 12 handles with curl_init(), configure them, create one curl_multi_init() handle, pass all 12 handles to multi handle with curl_multi_add_handle() and call curl_multi_exec(). after successful execution of requests, i curl_multi_remove_handle() all handles from multi handle, close them with curl_close(), and close multi handle with curl_multi_close(). After repeating this sequence 100 - 200 times, i get lotsa memory leaks and even crash.

Expected result:
----------------
No memory leaks. No crash.

Actual result:
--------------
Memory leaks, crash at offset 00018ed8
