Hi Noam,

I have a meta-question that originated from this bug. I was able to
reproduce this bug on an emacs session run in gdb and I even used the
-ggdb3 -O3 switches when building emacs. But I was unable to get any
backtrace[1] like you do here[2].

Any tips to what I am doing wrong here? [1] has details on what I tried to
do in gdb to get the backtrace.
