I ran ssh-keygen with strace and found that the seg fault occurs
after /dev/urandom is opened, then closed, and the "brk0x..."
lines come out. All the libs are present and appear fine. I ran
ssh-keygen with gdb too, and it doesn't have the debug stuff
compile in. I just a message stating the seg fault occurs when
working with libcrypto and libc.
I'm going to try compiling from source and see how that goes.
