Hello,
I basically use curl to upload realtime images to a remote server
and somehow there's a segmentation fault occuring inside.
I attached the stack trace, the way I use it and versions and other software
I integrate it with.
I've also seen a crash bug similar to this in sourceforge. It said use
version
7.21.0 because it already has a lot of fixes in Curl_Expire , but I'm
already using 7.21.1
=========================
