Subject: bug#10489: 24.0.92; dired-do-copy may create infinite directory hierarchy
Date: Thu, 12 Jan 2012 20:35:19 +0100

Hello,

start emacs -Q.

Suppose you have a directory "~/Test".  Do C-x d ~ RET.  Jump to the
line showing "Test".  Hit C and enter "~/Test".  Answer "yes" to the

 Recursive copies of /home/micha/Test? (yes or no) 

question.

This creates an huge recursive hierarchy of "Test" directories

  ~/Test/Test/Test/Test/Test/Test/Test/Test/Test/Test/Test/Test/...

The error

  copy-directory: Variable binding depth exceeds max-specpdl-size

finally stops that.

The user may do something like that per accident.  Emacs should IMHO not
behave like that.

The problem also appears in Emacs 23.


Thanks,

Michael.
