Bug #38686 Aborted when fetching https
Submitted: 2006-09-01 23:54 UTC Modified: 2006-09-03 09:19 UTC

Avg. Score:2.0 ± 0.0

From: php at cakkie dot be Assigned:
Status: Not a bug Package: cURL related
PHP Version: 5.1.6 OS: Debian
Private report: No CVE-ID: None

Description:
------------
When trying to fetch a page using https, it shows following error when calling curl_exec:

*** glibc detected *** free(): invalid pointer: 0x40158640 ***

This only happens when calling the PHP file from the commandline, and only when trying to fetch pages on https. 
When running the file through Apache 2.2.2, it works without a problem.
When fetching from http instead of https, it works without a problem.

Reproduce code:
---------------
<?php
        $url = "https://someserver/somefile.ext";
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_HEADER, 0);
        curl_exec($ch);
        curl_close($ch);
?>


Expected result:
----------------
running from commandline:#> php test.php
This is the contents of https://someserver/somefile.ext

running from browser:#> http://myserver/test.php
This is the contents of https://someserver/somefile.ext



Actual result:
--------------
running from commandline:#> php test.php
*** glibc detected *** free(): invalid pointer: 0x40158640 ***
Aborted

running from browser:#> http://myserver/test.php
This is the contents of https://someserver/somefile.ext

Forgot to mention:
I'm using libcurl3-dev_7.15.5-1

The commandline version of curl is able to fetch from https without a problem.

I've tried the latest snapshop (php5.2-200609020830), but the error is still there.

Can you please generate a backtrace?

Thanks
