Emacs ruby-mode hanging

[Guillaume Marcais]

There must be an endless loop in ruby mode on Emacs. I enter the
following text:

case toto
when 1 ||

Then the cursor is on the line after 'when ...', I press Tab and it
hangs showing me an hour glass forever, eating up 100% of CPU!

$ emacs -version
GNU Emacs 21.1.1

ruby-mode is from ruby-1.8.1 distribution plus patch from
ruby-talk:90977.

Hmm, Emacs 21.3.1 with ruby-mode.el from CVS HEAD works fine for me.

I just installed Emacs 21.3.1 and ruby-mode.el from CVS HEAD, it still
crashes for me.

Let me rephrase my original message as I realize it can be confusing.
The cursor has to be on the next line, on line 3 in the little example.
Then, when I press tab, it hangs. (With cursor on line 2, it is OK).

Can anybody reproduce this behavior?

Guillaume.
