I guess that the compressed packets are actually not completely correct,
and that the server thus never sends any reply.
Can you also enable transport layer tracing, and look at the
difference in output between libssh2 with and without zlib?
Possibly add debugdump() calls around/after compression in transport.c,
look for this line:
rc = session->local.comp->comp(session,
The next step would then be to manually decompress/decode the packets
as sent by libssh2 built with zlib, to validate whether they are actually
correct. The list might be able to help with that if you post output
from added debugdump() calls.
Kind regards
