* util.c (rv_alloc, freedtoa): use our normal xmalloc()/xfree() because

	  couldn't free the returned pointer from ruby_dtoa().

	* missing/vsnprintf.c (cvt): receive buffer and use/return it instead
	  of returning the pointer returned from BSD__dtoa().

	* missing/vsnprintf.c (BSD_vfprintf): pass buf to cvt() as the buffer.
	  [ruby-core:22184]
