Here's a strange one. In bash in i686, try to run:
ls /dev/ptmx
I only get about as far as:
ls /dev/p
and then my terminal window vanishes. This happens:
* In fish or bash.
* On two different hosts that I've tried.
* In mintty or a system terminal. In the system terminal, sometimes the
command works normally the first time, but fails the 2nd time; or I have to
press <TAB> after `ls /dev/p`, then the terminal vanishes.
* With other commands that treat their arguments as files, not text. So for
example, I can't finish typing `cat /dev/ptmx` or `test -r /dev/ptmx`
before the terminal window vanishes, but `echo /dev/ptmx` works normally.
It doesn't happen:
* In x86_64 - only i686.
* In scripts - only interactively.
Is anyone else able to reproduce this? I've tried to capture an strace log,
but I've failed so far. The strace seems to stop the crash. Still trying.
I thought this could be a BLODA problem, but the two hosts I tried are
running different virus scanners (McAfee and Windows Defender).
Cygwin 3.1.7-1, all packages up-to-date. Output of cygcheck -svr attached.

I think I fixed it. I just uploaded new developer snapshots to
https://cygwin.com/snapshots/ Please give them a try.
When I substitute cygwin1-20090909.dll for cygwin1.dll in i686, I can't run
any commands. They all give "The application was unable to start correctly
(0xc0000022)". Anything different I should be doing?
Check the permissions on cygwin1-20090909.dll. Is it executable?
