libssl is actually compiled 3 times.  Ones for the default
architecture which is i486, once for i586, and once for
i686 with cmov.  The dynamic linker should pick up the correct
one.

Can you verify that which version you pick up?  You can see this
with:
ldd /usr/bin/openssl

Can you also show /proc/cpuinfo?

openssl also contains hand written assembler, which detects cpu
capabilities as well.  Maybe something is broken there.

In any case would it be useful if you could give information
about which function it was that has the problem.  Can you
install libssl1.0.0-dbg and run whatever you wanted to 
do from gdb and give me a backtrace?
