emacs unexmacosx.c aborting during build

[Kendall Shaw]

I'm trying to install emacs +gtk and it barfs with a display of  
registers and memory followed by:

Assertion failed: (filesize <= ranges->size), function  
unexec_regions_recorder, file /Users/kshaw/Desktop/Source/emacs-22.1/ 
src/unexmacosx.c, line 454.
make[1]: *** [emacs] Abort trap
make[1]: *** Deleting file `emacs'
make: *** [src] Error 2


Do you know a fix?

Incidentally, I tried building from source from downloading the tar  
and I get the same error during the build.
