I've recompiled screen for Cygwin 1.7. It runs fine until I do the following:
* Open a cmd console and run c:\cygwin-1.7\bin\bash.exe --login .
* Start a new screen session (screen).
* Detach the screen session (C-a d).
* Exit bash.
* Try to start bash again.
Then I get:
3 [main] bash 212 c:\cygwin-1.7\bin\bash.exe: *** fatal error - Can't
create master tty
The problem continues until I kill the detached screen process and all of its
child processes.
This problem doesn't occur with Cygwin 1.5, of course. strace output is below.
If you'd like to try to reproduce it, you can download my binary screen package
for 1.7 from
http://home.comcast.net/~andrex/cygwin-1.7/screen/screen-4.0.3-1.tar.bz2 .
I Googled around and found a similar problem report from 1.7.0-3, at
http://www.mail-archive.com/cygwin@cygwin.com/msg87495.html . That one seems to
have spontaneously gone away.
N.B. no cygcheck -svr here, since cygcheck seems to be totally broken for me in
1.7-- see next message.
Thanks,
Andrew.
