Re: my program compiled by GCC crashed

Hi Andrew,

Thanks a lot for your reply.

Yeah, I agree with you.  There may be something wrong with
libicuio.so.3 or something else.

But we can not say it is nothing to do with GCC. I changed the
compiler from g++ to gcc(of course, I also changed to use stdio.h and
printf), then the core dump went away. With the same code and same
options for the comiler, when I went back to g++, it still cored.  How
can we explain that?


Thanks,
James
