segv in redisplay

[Robert Mecklenburg]

After a fresh checkout at 8/23 8:00am MDT and make bootstrap I am
getting a segv when I run M-x compile.  I've configured this command
to always display the output in a new frame.  Here is the data I
gathered:


Program received signal SIGSEGV, Segmentation fault.
