Hi folks, I encountered an weird issue when I using gcc 3.4.6 to build our project. The profile data (*.gcda files)can not be generated or be updated when the binary is running as 1 process, only be generated or be updated with 2 processes when I set the process number as 2 in the configure file. The configure options are exactly same except the number of PROCESS. (-fprofile-generate)
I am so confused. I have exactly same configure files, same code source, same machine and same environment, And this issue never happened when I was using gcc 3.2.3. I was trying to write a demo programme to reproduce it, but I failed, and I have no ideas what happened? So I write to you for help, please tell me any possibilities may lead this issue happen? Thank you very much rgds Hui
