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. ########## excerpt from "strace inetd -d" with
