I would expect the bug to lie in the multi-precision arithmetic
package.  The key-generation phase starts by finding numbers which are
prime and have some other properties --- if this code is misbehaving it
may well be that no suitable numbers are ever found, which would cause
key-generation to "hang".  And then, of course, I'd expect the connection
setup handshaking to fail on mathematical grounds, too...

I'd check crypto/bn in the openssl package carefully.  Esp the 'asm'
directory.  Trying to turn the inline-asm optimizations off might be a
good first step.

It may very well be due to similar math errors?  I can't find any
libraries octave2.1 and ssh have in common, though.
