[Bug c++/17323] ICE on invalid code if static member array initialized with size computed as division by zero

hmm, the problem looks like it has nothing to do with sizeof at all but it has to do with DECL_INITIAL 
for x still being an INIT_EXPR so we check the first operand for value_dependent_expression_p but 
since that just links back to x, we go into an infinite loop which causes this ICE (stack overflow).
Maybe we should have cleared out the DECL_INITIAL and put a error_node there instead.


Part of the backtrace (I cannot get all of it because it is just repeating two parts of 
alue_dependent_expression_p)

#40392 0x080eab2d in cp_parser_type_specifier (parser=0xf6e128f0, flags=Variable "flags" is not 
available.
) at /home/gates/pinskia/src/gnu/gcc/src/gcc/cp/parser.c:12809
warning: Source file is more recent than executable.

12809       CLASSTYPE_DECLARED_CLASS (type) = (class_key == class_type);
(gdb) up -1
#40391 0x080776e1 in xref_basetypes (ref=0xf6e14074, base_list=0xf6e13180) at /home/gates/
pinskia/src/gnu/gcc/src/gcc/cp/decl.c:9136

Also gdb just seg faults on me alot when going through all these stack frames (yes I am using the cvs 
version, I should report a bug).
