Hello,
After reconnecting to rcirc, my emacs stopped responding. Hitting C-g
let me enter gdb. I hit "fin RET RET RET" until emacs stops responding
again, and found that I could not finish re_search_2. Here's the
backtrace (hand-edited to remove the value of "targets" which was
uselessly long):

The advice on recenter most probably is this one :
(defadvice recenter (before backtrace activate)
(let ((inhibit-read-only t))
(with-current-buffer "*Messages*"
(when (looking-back "[^\n]")
(insert "\n"))
(insert
(format "Recenter backtrace: \n%s"
(yf/light-backtrace))))))
I'll admit that (looking-back "[^\n]") is not exactly the canonical way
to test for (not (bolp)), but should it make an infloop ? I can't
reproduce though.
I'll keep the gdb session around for the time being.
