Did you upgrade OpenSSL? It looks more like a problem in OpenSSL so I suspect
just upgrading libcurl won't help for this.

Further, if the problem remains I think you should consider building custom
versions of libcurl and openssl with debug systems present so that future
crashes get more details provided. I'd also urge you to try to come up with a
way to reproduce the problem since just randomly occuring crashes are
notoriously hard to work with.
