I have the same problem. I notice it's only been reported on NT 4.
Corinna and Chris, are you unable to reproduce it on NT4, or are you
not running NT 4?
I ran "inetd -d" on the command line under strace. In
Cygwin-1.3.10-1, login does not manage to startup bash. Here are two
sections of strace output. Each begins after login reports that it
has spawned a process, through to when login reports back again. In
1.3.9-1, it's child is alive (successful login), but in 1.3.10-1, its
subprocess has exited (bash never started -- at least, no bash
reported anything to strace).
The first difference is in 1.3.10-1, with:
201 4347865 [main] in.telnetd 343 fhandler_socket::send: Fallback to winsock 1 send call
Does this indicate a problem? Does it help to diagnose it? I can
trace more, if someone tells me what to trace, what masks to use (if
any), etc. Unfortunately I'm not in a position to build a DLL here.
