Understood, though my point was that things worked in the very old version,
and newer ones do not.

I did some more testing. I reverted the PHP lib back to 0.10, with no
change in behavior on libssh2 1.1. Same problem.

I tested back to 1.0, 0.18, and finally back to 0.13. The problem went away
with 0.13.

Fine, though it's the older version that appears to be working okay.

I'm not sure why you don't find it curious, then - it's the older version
that works fine. The newer versions are where problems are seen.

If you'd convert your program to a plain libssh2 example I would perhaps be
able to answer those questions. Speaking in PHP terms isn't making this very
easy for us...

I'm not sure if I'll have the cycles myself to do this, but I'll see what I
can do. In the meantime if you have any other debugging suggestions, let me
know. If the problem only happens with the PHP library, what would you
suggest I do/contact?
