./miscd killuser
Segmentation fault

不知道为什么， 我这里bbs启动都没有问题，查询用户也没问题，flush也可以，但是就是killuser不行：

Breakpoint 1, main (argc=2, argv=0xbfa342c4) at miscd.c:687
687             if (strcasecmp(argv[1], "killuser") == 0) {
(gdb) n
688                 if (resolve_ucache() != 0)
(gdb) n
690                 return dokilluser();
(gdb) s
dokilluser () at miscd.c:165
165         newbbslog(BBSLOG_USIES, "Started kill users\n");
