test.sh fails on the openssl test for me too.  I can't really follow
exactly what the testcase is doing though.  It looks like there's a race
condition somewhere because you get the previous command's output with
each command:

$ socat -t0.1 exec:'openssl s_server -accept 12009 -quiet -cert
cacert.pem -key privkey.pem' pipe &

$ echo -n "1" | socat -t0.1  -
openssl:localhost:12009,cafile=cacert.pem,verify=1

$ echo -n "2" | socat -t0.1  -
openssl:localhost:12009,cafile=cacert.pem,verify=1
1
$ echo -n "3" | socat -t0.1  -
openssl:localhost:12009,cafile=cacert.pem,verify=1
2
$ echo -n "4" | socat -t0.1  -
openssl:localhost:12009,cafile=cacert.pem,verify=1
3

I don't know what's going there.  You'd probably have to delve into an
strace to find out.
