Summary: php_curl init time (3 big seconds)
Status: Open
Type: Bug
Package: cURL related
Operating System: Win7/Vista x86
PHP Version: 5.3.4 (Since 5.2.14/5.3)

New Comment:
btw, I just applied this change to my tree as well:
https://github.com/pierrejoye/curl
nmake /f Makefile.vc9 WINDOWS_SSPI=1 USE_IPV6=1
WITH_DEVEL=g:\php-sdk\lib_builds\vc9\x86\deps
CFG=release-ssh2-ssl-dll-zlib
to build it for PHP's VC9 (with almost all protocols, incl. ssh2). As
long as you copied the dependencies in ..\deps (like for php's builds).

As I said, the libcurl previous release (for our build only) has been
modified to do not call this function anymore. The latest libcurl
release should have the fix too.

Just to confirm :
I tried all 5.3.4 and 5.2.16 versions (TS/NTS VC6/VC9), even a self
compiled one
from sources and the problem always appears on Vista and Seven x86
I posted a bug report to curl team... but i cant find RAND_screen() call
in their
lastest release...

Ok, hmm after a night of debug, i think the code is in the static
libcurl_a.lib
i've tried to build a module with standard libcurl dlls (php_curl of
64k).... but
seems to have a bad address for the curl_global_init() call
I think we need to follow this issue to curl team :p

If you want to try the difference, here is the patched php_curl dll.
http://tanguy.wdscript.fr/files/php_curl.534vc6ts.Patched.zip
I'm now compiling php with openssl comment... to check if its the cause
of the
problem... i dont understand why this code is in php_curl dll code...

Here is an asm dump of lib_curl.dll 5.3.4 VC6 TS where RAND_screen is
used :
0035DB10 > \E8 FF360100 call <jmp.&SSLEAY32.#74>
0035DB15 . E8 F4360100 call <jmp.&SSLEAY32.#183>
0035DB1A . 85C0 test eax, eax
; kernel32.BaseThreadInitThunk
0035DB1C . 75 01 jnz short php_curl.0035DB1F
0035DB1E . C3 ret
0035DB1F > E8 E4360100 call
<jmp.&LIBEAY32.#3212_OPENSSL_add_all_algorithms_noconf>
0035DB24 . E8 D9360100 call <jmp.&LIBEAY32.#468_RAND_screen>
0035DB29 . B8 01000000 mov eax, 1
0035DB2E . C3 ret
A simple replace of E8 D9360100 by 90 90909090 will fix the problem...
but maybe
a call to the regular rand() function could be needed elsewhere...
