From what I can see the failure is related to pipes:

   41  673146 [main] ssh 4392 cygwin_select: 7, 0x100EEBF8, 0x100EEB70, 0x0, 0x0

   71  674559 [select_pipe] ssh 4392 peek_pipe: , PeekNamedPipe failed, Win32 error 109

109 is "The pipe has been ended". Isn't that strange when reading a pipe? 
Unfortunately fd 4 was opened in a part of the trace that we don't have.
Sending a url to the full trace is more useful (and less controversial)
than sending parts.
