I cannot believe that this function per se is the root cause of the problem. However the simple fact that its definition takes some memory space suffices to increase the likelihood the crash when I open that file.

Is this doit-1 function actually used somewhere in your init.el or in
your .emacs?  If it is, can you show the code that uses it?

> BTW, here is the end of my *Message* buffer when the opening of  USING_CEDET_FROM_BZR does cause any crash, this reflects what should happen when this file is visited --- the `Loading dired-x...done' is because I open  USING_CEDET_FROM_BZR from a Dired buffer, so what happens is from line    `flet' is an obsolete macro (as of 24.3); use either `cl-flet' or `cl-letf'. [2 times].

Can you turn on debug-on-error and show the Lisp backtrace for these
messages?  Each time a backtrace appears, type "C-]" to get out of the
debugger and continue to the next error.
