> With latest CVS cygwin1.dll:
> I click cygwin.bat, and bash opens.
> I click cygwin.bat again and a console window opens, but the bash prompt
> does not appear.
> Further investigation with strace shows that the second instance of bash
is
> getting signal 21 (SIGTTYIN) over and over again.
> If the second instance of bash is launched using cygwin.bat from the
cmd.exe
> command line, the same problem occurs.
> If bash is run as "bash --login -i" from c:\cygwin\bin from the cmd.exe
> command line, the bash prompt appears.
> If SET CYGWIN=tty is typed before running bash directly from the cmd.exe
> command line, the bash prompt does not appear and an strace shows the
signal
> 21 problem.
>
> So it seems that setting the tty flag in the CYGWIN environment variable
> causes the second, third, fourth, etc. instances of bash to go into an
> infinite loop receiving SIGTTYIN.
