Re: emacs doesn't compile (again)

Oh yeah, "info frame" is always good too.  There is definitely some funny
business here.  The reported faulting eip value is in the middle of an
instruction.  You're going to have to watch it happen.

e.g.

b ralloc.c:514
comm
cont
end
run

Then "i b" after the crash will show you how many times it hit (N),
then you can do "ignore <bkpt#> <N - 1>" (and reset the bkpt commands),
run again, and step through until the badness happens.
