Comment 2 for bug 1096826

I'm seeing this same valgrind error when using libcurl4-openssl-dev, ostensibly because libcurl is making similar calls to the ones suggested by the OP.

The "issue" seems to be realted to a glibc change to the way some sendmsg() variables are handled: http://sourceware.org/bugzilla/show_bug.cgi?id=14687.

The solution may be to update the valgrind suppression files to include this "error" as opposed to "fixing" glibc.
