Package: libssl0.9.8
Version: 0.9.8b-1
I've got a SparcStation 20 with two cacheless CPUs. I can't make
ssh connections with newer libssl0.9.8 versions than 0.9.8a-8.
The problem appeared with the first 0.9.8b release and the newest
version I've tried is 0.9.8c-3, where it still fails. Also sshd
seems to suffer from this same problem.
I've tried connecting against more than one type of UNIXen,
sshd implementations, endianness platforms, etc. The result
is pretty much the same, so the problem can't be with the
other boxes.
I've also got several SparcStation 5's running Debian/unstable
and so far I haven't noticed any problems with them.
Is there some new hand optimized assembler code for sparcs
in libssl these days? If not, then I suspect that the problem
is with the gcc version used to compile the official packages
these days. I haven't got the resources to try out different
compiler versions though.
<opinion type="personal">gcc 2.95 is a lot more reliable on sparcs.</opinion>
Here are some cut'n'pastes that I hope will be helpful:
