imenu freeze in texi

[Daniel Pfeiffer]

In a texi buffer (e.g. man/ack.texi or man/programs.texi) in emacs -q

(imenu-add-menubar-index)

causes Emacs to freeze.  It doesn't even react to C-g or a window manager
close request.  Strace shows it to be in a rapid endless loop of:

--- SIGALRM (Alarm clock) @ 0 (0) ---
gettimeofday({1100365566, 98}, NULL)    = 0
gettimeofday({1100365566, 197}, NULL)   = 0
gettimeofday({1100365566, 289}, NULL)   = 0
setitimer(ITIMER_REAL, {it_interval={0, 0}, it_value={0, 99809}}, NULL) = 0
sigreturn()                             = ? (mask now [])

where only the it_value varies slightly.
