所有软件都是最新的，gdb跟踪好像错在memcpy

(gdb) run --search cac

虽然自己调试最后肯定可以找出错误，不过我还是想看看有没有人先解决了

似乎和locale有关

tclwp

果然
#export LC_ALL=en_US
#export LANG=en_US
# slapt-get --search sendmail
procmail-3.22-i486-2 [inst=yes]: procmail (mail processing and local delivery program)
sendmail-8.13.8-i486-4 [inst=yes]: sendmail (mail transfer agent)
sendmail-cf-8.13.8-noarch-4 [inst=yes]: sendmail-cf (configuration files for sendmail)

问题解决啦:cool: :cool: :cool: :2cool

这是作者的回信：
Odd,

If you remove the following line from /var/slapt-get/package_data the problem goes away:

aspell-pa: GNU Aspell 0.60 Punjabi (ਪੰ~\ਾਬ~@) Dictionary Package.

It looks like the regexec() call in GLIBC is barfing on that line:

I'll take a look and see what I can do.
