[Bug 241331] Re: Running a non-existing command in the background causes exit

 

I found out that though the bug is pretty reproducible on long path lengths, for short path lengths, the bug is sometimes reproducible, but sometimes not.
Test case: 
1. Open an xterm with a bash.
2. Make sure that the command q is not present on your system.
3. cd / [Enter]
4. q & [Enter]

Continue doing 4. until your bash exits. I needed 66 attempts for the root directory "/" and command "qqq". With the command "q" it was 51 attempts.
The tested locale is de_DE.UTF-8 for LANG, LC_..., and LANGUAGE on ubuntu, 
bash has version 4.3-7ubuntu1.3,
xterm has version 297-1ubuntu1.
Since the behavior is not deterministic on the user input, it looks like a memory corruption issue or a race. Any help?

Title:
  Running a non-existing command in the background causes exit

Status in “bash” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: gnome-terminal

  In Ubuntu 8.04, running a command which does not exist can sometimes
  cause an exit command.  Here is an example cut and pasted when gnome-
  terminal is set to "stay open on exit".

  richard@sepulchrave:~$ gedit test &
  [1] 13336
  richard@sepulchrave:~$ gdit test &
  [2] 13340
  richard@sepulchrave:~$ exit

  Other times  the exit will not happen but the command will return an
  Exit 127 status.

  richard@sepulchrave:~$ gdit test &
  [1] 13403
  richard@sepulchrave:~$ bash: gdit: command not found

  [1]+  Exit 127                gdit test
  richard@sepulchrave:~$ gdit test &
  [1] 13405
  richard@sepulchrave:~$ exit

  Package is
  gnome-terminal:
