That version was released in early 2013. We've done almost *12,000* commits
and 72 releases since then.

I presume your OS vendor has patched the *60* individual security
vulnerabilities that are present in the original version of that release [1],
which then also has converted it into a frankencurl version you cannot expect
that anythone else than the centos maintainers can take responsiblity for.

This is not only a newer curl release, you're also comparing with a curl built

That commit just removed the entry from KNOWN_BUGS. It doesn't actually say
or hint about when the exact fix was done.

Besides, I'm not convinced you'll be much happier even if you figure out the
exact commit that made it work: You still need to update and why then make the
situation even more complicated by patching a frankencurl instead of just
going to a much much newer version anyway?

If you really want to find the exact commit, I think bisecting is the only

I don't know anything about centos and centos repositories, but I know that
building a modern curl from source is usually possible and a viable
alternative even on these outdated systems.
