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?
