It is commonly called an ICE. This acronym means Internal Compiler
Error. As the acronym suggests it is a problem in your compiler,
probably too much optimisations turned on. Defaults should work on gcc
2.95.3, gcc 3.2.x, gcc 3.3.

Even if i'm not against gcc  2.96 (shiped with some mandrake and red hat
systems), this  version has lot of  errors like the one  you mention, if
you are using a gcc 2.96, consider upgrading to a gcc 3.[23] version.

If this is not your case, then disable some optimizations manually in
the  created platform.inc  or  specyfying them  directly at  ./configure
time. 

$ CFLAGS="-O2 -fomit-frame-pointer ....." ./configure
          ^^^^^^^ put here what you want/desire, makes gcc compiles the
	  sources well
