PHP Bug Type: cURL related
Bug description: Segfaul when using certain curl_setopt option
Description:
------------
Hello,
I have found a bug which crashes PHP when using CURLOPT_FOLLOWLOCATION.
This happens on certain adresses only, the one specified in the example
later gives a crash.
Example line:
curl_setopt ($curl_handle, CURLOPT_FOLLOWLOCATION, 1); // <<< CRASH HERE
I don't know my configure line exactly. Anyway, I compiled PHP by hand
with--curl and --with-mysql and --with-cli. Rest is as untouched.
Unique to my systems where the problems I had getting mysql5 working. It
seems there is a bug in the configure Script of PHP which makes it ignore
the 64bit Libraries of mysql. I had to copy /usr/lib64/mysql to
/usr/lib/mysql to make compiling work.
The problem is indenpendant from the php.ini, I tried different one. The
default configuration also produces the crash.
Reproduce code:
---------------
<?php
$curl_handle = curl_init();
$timeout = 10;
curl_setopt ($curl_handle,CURLOPT_URL, 'www.vipnet.at');
curl_setopt ($curl_handle, CURLOPT_FOLLOWLOCATION, 1); // <<< CRASH HERE
$buffer = curl_exec ($curl_handle);
print_r ($buffer);
?>
Expected result:
----------------
