Help wanted

[Jane Liang]

Hi, all:

I have a simple program(see below), it ran without any problem in sun (with
sun's compiler). However, when I compiled it in gcc on PC, it crashed at
line 13.  I tried to use strtok and some other string functions but none of
them seems works fine.  Does anyone know why?

Thanks!

Jane
