openssh-portable segmentation faults

Would it be possible if someone with a FreeBSD 9.1Stable system built after 2-Feb could build and run openssh-portable.

Segmentation faults are occurring with both ssh, and sshd built today on both i386 and amd64 machines.

A portsnap was performed and built all ports on 4-Feb. The openssh issue was picked up during pre-deployment testing. We then
performed another portsnap, which updated openssl, hence the openssl 1.0.1.d below; it also failed using 1.0.1c.

Starting from the default options, each option was turned off, and rebuilt until there was only one option OVERWRITE_BASE=on.
