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
