You didn't mention what libcurl version you use, but clearly this is built to use NSS for the SSL layer so I guess you're using a Fedora-provided library. There's already at least one NSS-libcurl-git related bug report[*] for Fedora submitted and I think you'll have a reason to follow that to see if you can help them or they can help you. To me this looks like at least one NSS bug. In the mean time I suggest you attempt a work-around: build a new libcurl powered by another SSL library such as OpenSSL or GnuTLS. It's just a matter of running libcurl's configure with the proper command line [*] = https://bugzilla.redhat.com/show_bug.cgi?id=483222 -- / daniel.haxx.se
