Re: scp on MS-Windows, using pre-built 0.5.0

[Aris Adamantiadis <aris@xxxxxxxxxxxx>]

Hi Colin,

What would be interesting is to run libssh in verbose mode so we get
some feedback on what's happening under the hood. The stacktrace is not
very useful in this case because we can expect the hang to be in the
poll loop. It's more useful to understand why it's expecting something
to happen.
My bet: 0.5.0 had some issues with big downloads because of
renegociation problems, that has been fixed in 0.6rc. Could you check ?

I'm afraid we do not have any other precompiled binaries but we should
invest some time at providing them.
