Subject: login crashes
Mime-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit


I run login with a username: login blahblah,
then I type something on password prompt,
login says 'Login incorrect',
on the next login prompt I press Ctrl-D and login crashes with the
message:

login:       0 [main] login 1160 handle_exceptions: Exception: STATUS_ACCESS_VIOLATION
   9413 [main] login 1160 stackdump: Dumping stack trace to login.exe.stackdump

   
If I type something on the second login and password prompts and
press Ctrl-D on the third login prompt then login exits normally
without crash.


cygwin versions 1.1.2, 1.1.3-1
login versions 1.3, 1.4-1
