* parse.y (parse_regx): should raise error on untermitated
expression interpolation. * pack.c (pack_unpack): should give length to utf8_to_uv(). * pack.c (utf8_to_uv): add length check. * massages: replace "wrong #" by "wrong number". * marshal.c (w_float): output Infinity and NaN explicitly. * marshal.c (r_object): support new explicit float format. * eval.c (rb_thread_wait_for): select may cause ERESTART on Solaris. * eval.c (rb_thread_select): ditto. * array.c (rb_ary_join): dumped core if sep is not T_STRING nor T_NIL. * array.c (rb_ary_join): buffer size calculattion was wrong. * array.c (rb_ary_to_s): if rb_output_fs is nil, insert newlines between array elements (use rb_default_rs as newline litral) [experimental]. * gc.c (init_mark_stack): no need to clear mark_stack. * gc.c (gc_mark_all): need to handle finalizer mark. * gc.c (gc_mark_rest): use MEMCPY instead of memcpy. * gc.c (rb_gc_mark): earlier const check to avoid pusing special constants into mark stack. * numeric.c (fix_to_s): 'to_s' now takes optional argument to specify radix. [new] * bignum.c (rb_big_to_s): ditto. [new] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@1842 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
