System: Linux stag.telekinesys 2.2.17sk #14 Thu Nov 30 20:11:50 GMT 2000 i686 unknown
Architecture: i686

	
host: i686-pc-linux-gnu

>Description:
	cc1 crashes in build_function_type (called from ix86_init_builtins)
	if '-msse' is passed on the command line. A null pointer (value_type)
       	is dereferenced.

>How-To-Repeat:
	Simply run 'cc1 -msse'. It does not even begin parsing input.
	Backtrace is
