标题[公告] 关於 HW#5 libcmd.a 的更新
时间Mon Dec 25 16:33:58 2006
如果你对前面几篇文章关於 libcmd.a 的一些问题, 没有搞的很清楚的话, 请看这里---
1. (见 posts 334 337)
如果你遇的 crash 是 ---
0x0092a9b7 in __gnu_cxx::__pool<true>::_M_reclaim_block ()
from /usr/lib/libstdc++.so.6
I then googled "__pool<true>::_M_reclaim_bloc". It seems that other people
have the similar issue. And some people think that it is due to some version
of g++ is not happy with some version of libstdc++...
Anyway, 请下载 platform-dependent "libcmd.a".
Under <classWebsite>/Homework/, you can download...
-rw-r--r-- 1 ric faculty 57290 Dec 25 16:10 libcmd.a
-rw-r--r-- 1 ric faculty 102226 Dec 25 16:13 libcmd.a.4.0
-rw-r--r-- 1 ric faculty 74002 Dec 25 16:16 libcmd.a.ccws2
where "libcmd.a.4.0" is compiled under a g++ version 4.0 machine, and
libcmd.a.ccws2 is compiled under ccws2, and libcmd.a is the original one.
Choose a suitable libcmd.a for yourself.

The bug ---
ltest> q
Are you sure to quit (Yes/No)? [No] // 直接按下 enter
terminate called after throwing an instance of 'std::out_of_range'
what(): basic_string::substr
Aborted
is fixed and included in the above new libcmd.a.
You don't need to download this if you don't have the crash in (1).

For a quick workaround, I've changed the READ_BUF_SIZE and MAX_HISTORY
65536.
Download this if your script may have more than 1024 commands.
