 If I'm right the bug is in the part 

#ifndef READ_DATA_PENDING_PTR
	if ((*bp++ = c) == delim || bp == bpe) {
	    cnt = bp - buf;

	    if (cnt > 0) {
		if (!NIL_P(str))
		    rb_str_cat(str, buf, cnt);
		else
		    *strp = str = rb_str_new(buf, cnt);
	    }
	    bp = buf;
	}
#endif

 it use a 64 bit ruby/Solaris and in its case READ_DATA_PENDING_PTR is not
 defined.

 Now `c' never equal `delim' (because it don't have a newline at the end),
 and  bp != bpe (it read only few characters) this mean that *strp is never 
 created if I'm right
