It seems that I compiled now the error checking enabled emacs. BTW I
just found out that even for the vanilla compiled emacs there is bug
trace file in /tmp, however its around 300 Mega, so basically worse less
so I continue to give the error enabled emacs a try.

But I still don't get it to work. I do

 cd src/emacs/src (dir where the new emacs is compiled)
 gdb
 run /home/oub/src/emacs/src/emacs

un /home/oub/src/emacs/src/emacs
Starting program:  /home/oub/src/emacs/src/emacs
No executable file specified.Use the "file" or "exec-file" command.

exec-file /home/oub/src/emacs/src/emacs

And nothing happens.

What do I miss?
