 Hi,
 
From: "NODA, Kai" <no...@gm...>
Subject: [Mlterm-dev-ja] Bug#640180: mlterm: Double free in ml_bidi_copy()
Date: Fri, 09 Sep 2011 04:40:34 +0900
Message-ID: <20110908194034.18493.60615.reportbug@zbox>

 Thanks very much.
 I merged your patch, which I fixed a little because I think
the first argument of memcpy() could be NULL.

 ありがとうございます。御指摘のとおりです。
 修正をとりこませていただきます。

 今後ともよろしくお願いします。

# Double free 問題についてもありがとうございました。
# size が 0 になるケースを想定しておらず、しょうもないミスをしてしまいました。
# realloc() は size が 0 だと、単に free() するんでしたね。

Fixed a memory corruption.

In x_get_all_config_font_names(), when size == 1 and d_size == 0 and
array[0]->key == DEFAULT_FONT, neither strcpy() nor sprintf() are done, thus
p is left at the first character of the blank buffer font_name_list.
In that case it's wrong to do simply *(p - 1) = '\0'.
