I would like to suggest a new feature: Add an option to disable profile usage
in case of profile missmatch.
While rebuilding libreoffice 4.3.0 with profile data to make it work faster on
my old CPU

I have two ld: GNU and GOLD.
Problem appears before ld call, but with such gcc keys ld GOLD must be called.
It version is GNU gold (GNU Binutils 2.22.0.20120323) 1.11.

(In reply to comment #8)
Surely not using -freorder-blocks-and-partition will fix this?
Yes, it fixes.
The actual
bug should not be LTO or PGO related.
