Description:
------------
Hello..
   I have a problem which crashes PHP when using HTTPS url.

Example: (HTTPS)  
   curl_setopt($cl,CURLOPT_URL,"https://login.yahoo.com");
   $out = curl_exec($cl); //ERROR

Example: (NO HTTPS)
   curl_setopt($cl,CURLOPT_URL,"http://login.yahoo.com");
   $out = curl_exec($cl); //It is OK!



Reproduce code:
---------------
[root@locahost ~] /usr/local/php5/bin/php test.php

test.php:
<?
$cl = curl_init();
curl_setopt($cl,CURLOPT_URL,"https://login.yahoo.com");
$out = curl_exec($cl);
curl_close($cl);
echo $out;
?>

Expected result:
----------------

Yes, thank you.
As you can see from the backtrace, the crash happens somewhere inside libcurl and it's not PHP problem.
Looks like a symbol clash between some libs.

Do you know yaSSL symbols come from?
What was your configure line?

My configure line:
'./configure' '--prefix=/usr/local/php5' '--with-mysqli=/usr/bin/mysql_config' '--with-mysql=/usr' '--with-apxs2=/usr/local/apache2/bin/apxs' '--with-config-file-path=/usr/local/php5' '--enable-mbstring=tw' '--enable-ftp' '--with-iconv' '--with-zlib' '--with-gd=/usr' '--with-jpeg-dir=/usr/local/lib' '--enable-exif' '--with-gd' '--with-jpeg' '--with-tiff-dir=/usr/lib' '--with-png' '--enable-track-vars' '--with-curl' '--with-freetype' '--with-xpm' '--enable-sysvshm' '--enable-sysvsem' '--enable-sockets' '--with-openssl=/usr'

I use "yum update" to update FC5,and It's happen :(

Aha, I see..
Looks like it's a bug in yaSSL. Try installing OpenSSL instead.
Anyway we're unable to help you in this case.

I found the problem is comes from MySQL5(RPM).
I remove MySQL5.0(RPM),and install MySQL4.1(RPM),this question solved?
