Sorry for bothering you, but I see now that bug still exists. My code
already had a workaround for that issue and I not disabled it when
testing against latest version (5.3.3RC3 and libcurl 7.21.0). Now
I've tested again with truly parallel 5 ftp requests and it is still
failing as it was with PHP 5.2.13 on Win XP SP3

Was a libCurl issue, fixed in latest release.

I&#38;#39;ve tested with latest PHP5.3.3RC3 downloaded from
http://windows.php.net/qa/ and it works fine now with 5 FTP and 3 HTTP
parallel requests using curl_multi_* functions. This request failed
before. cURL version is 7.21.0. It seems bug is fixed in latest curl.

Curl version: libcurl/7.20.0 OpenSSL/0.9.8h zlib/1.2.3
