If one tries to use the ‘in’ operator on a string*[] array, valac emits a critical warning and generates invalid C code.

For example:
    string*[] my_array = my_variant.get_strv ();
    var my_bool = ("foobar" in my_array);

results in the following compiler output:
    ** (valac:2432): CRITICAL **: vala_ccode_base_module_get_ccode_lower_case_name: assertion 'node != NULL' failed
    ofono-backend.c:215:17: warning: function declaration isn't a prototype [-Wstrict-prototypes]
     static gboolean _vala_(null)_array_contains (const gchar** stack, int stack_length, const gchar* needle);


This is caused by the following generated C code:
    static gboolean _vala_(null)_array_contains (const gchar** stack, int stack_length, const gchar* needle);
    …
    static gboolean _vala_(null)_array_contains (const gchar** stack, int stack_length, const gchar* needle) {
    	int i;
    	for (i = 0; i < stack_length; i++) {
    		if (g_strcmp0 (stack[i], needle) == 0) {
    			return TRUE;
    		}
    	}
    	return FALSE;
    }
