I finally got around to figuring this out.  The GCC 4.8.0 release
notes say that -O implies -fomit-frame-pointer on more platforms now.
Apparently i386 is one of them.  If I add -fno-omit-frame-pointer to
the build flags, and edit configure to remove the spot where it adds
-fomit-frame-pointer to the build flags, then the build succeeds.

I have no idea why that makes a difference.  The symptom was that the
value stack would overflow.  Is management of the value stack tied to
the program stack somehow?
