清水@biglobe です。

夏休みが終ってしまったので、試してみました。

$ uname -a
UNIX_SV host 4.2MP 1.release.0603.11:09 R4000 r4000
$ uversion
Release13.6 Rev.A - EWS4800/360PX - WS

という環境で、
ruby 1.6.4 (2001-06-04) [mips-sysv4.2]
です。
前回のサンプルスクリプトでは、私も問題の再現を見ませんでした。
が、3行あるコメントを外し、ソケットの読み書きをさせてやるとあっさり落
ちました。
前回いろいろ試した時は、読み書きなしでも落ちたような記憶があったのです
が、記憶違いかも知れません。

EWSで初めてgdbを使ってみました。情報になっているでしょうか。

Program received signal SIGSEGV, Segmentation fault.
0x4005109c in t_splay ()
(gdb) bt
#0  0x4005109c in t_splay ()
#1  0x40050ec8 in t_delete ()
#2  0x400503ac in _real_malloc ()
#3  0x4005017c in malloc ()

だったり、以下だったり、いろいろでした。
