From: martin at mixotv dot com
Operating system: Linux 3.4.8-1
PHP version:  5.4.5
Package:  cURL related
Bug Type: Bug
Bug description:curl_copy_handle segfault with CURLOPT_FILE

Description:

When using cURL with the option CURLOPT_FILE (write the result of the curl
request in a file), curl_copy_handle() causes a SEGFAULT.

I use the packages from Archlinux repository (php, libcurl 7.27.0 x86_64).

I get the same results with a current ubuntu distribution.
