SFU3.5下GCC编译dump,请高人看看是什么原因。

[stareyess]

在XP下安装SFU3.5，SDK组件完全安装。用户映射和telnet服务皆正常。
编译时出现如下错误：
% gcc -o test test.c
gcc: Internal error: Segmentation fault (program cc1)
Please submit a full bug report.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

用GDB解析core结果如下：
% gdb gcc core

This GDB was configured as "i586-pc-interix3"...(no debugging symbols found)...
Core was generated by `gcc -o test test.c'.
Reading symbols from /usr/lib/libc.so.3.5...done.
Loaded symbols for /usr/lib/libc.so.3.5
#0 0x00410805 in ?? ()
Segmentation fault (core dumped)

看起来似乎是在调用libc.so.3.5时出现了段错误。

test.c内容如下：
#include <stdio.h>

int main(){
printf("Welcome world!");
sleep(1000);
return 0;
}
试过编译空的C文件仍然出现同样错误。

重新安装了几遍SFU，现象依旧，然后不知道怎么办好了，
请高手们指点迷津，谢谢。
