In scp_recv function in ssh.c, libssh2_channel_read function is called which
returns ERROR_EAGAIN which is stored in variable 'nread'. This variable
nread is declared ssize_t (typedef __int64 for Windows 64 in
config-win32.h). For reason which I don't know of, nread has an arbitrary
current value of 4294967259 instead of expected -37 (ERROR_EAGAIN).
BTW, when I declared ssize_t as int (instead of __int64) in config_win32.h,
then the problem goes away and the file gets downloaded successfully.
In the public libssh2.h header the ssize_t is typedef'ed to an int. Isn't that
causing this problem?
I would expect that libssh2 needs something similar to this to start with:
