It seems that libssl/libcrypto are broken in -CURRENT just after GCC 4.2 import.
Binaries using these libs produce core in my core2duo (current).
i.e. apache2+ssl , postfix(tls) , and portsnap are some of them.

How to reproduce:

mail# portsnap fetch
Looking up portsnap.FreeBSD.org mirrors... 3 mirrors found.
Fetching snapshot tag from portsnap3.FreeBSD.org... Illegal instruction (core dumped)
invalid snapshot tag.
Fetching snapshot tag from portsnap1.FreeBSD.org... Illegal instruction (core dumped)
invalid snapshot tag.
Fetching snapshot tag from portsnap2.FreeBSD.org... Illegal instruction (core dumped)
invalid snapshot tag.
No mirrors remaining, giving up.

Something ugly lives inside these libs.
