Re: segfault at 0 ... error 4 in curl-loader

Robert,

In case you need it, here is the curl version:

curl 7.19.0 (x86_64-suse-linux-gnu) libcurl/7.19.0 OpenSSL/0.9.8h
zlib/1.2.3 libidn/1.10
Protocols: tftp ftp telnet dict ldap http file https ftps
Features: GSS-Negotiate IDN IPv6 Largefile NTLM SSL libz

Alternately, if you know of a version of libcurl which is more
stable/works better with curl-loader, I would happily revert to an
older version.

Your efforts are appreciated.
