It might.  One of the bugs fixed in that commit is that two simultaneous
references to the same memory cache would cause one of the references to
become a dangling pointer when the other is destroyed.  I'm not sure how
upgrading curl would lead to that scenario, though.

If you choose to backport this commit, note that it contained a bug,
