Problem when using profile-guided optimization

Problem when using profile-guided optimization

Hi everyone, I'm using the lastest ifort 12.1.5 and I'm tesing the pgo (profile-guided optimization) feature, but encoutered problems. Here's my program, a quite simple hello world:

program main print *, "hello" end program main 

then i compile it like this:

ifort -prof-gen hello.f90
then I run the program


and then compile it again:
ifort -prof-use hello.f90
but I got the following error message:
/tmp/hello.f90(1): warning #11507: Value profiling mismatch for 'MAIN__'.
Does anyone know why? did I miss something? Thanks.

For more complete information about compiler optimizations, see our Optimization Notice.

This looks like an extraneous warning message. I'll enter a bug report.

This thread is how you track this bug. When a fix is made I have to update this thread to let you know.

Closing this issue.  This was fixed in the Update 1 compiler, and confirmed fixed in Update 2 as well.
