Nice work Victor.
> Can we turn that particular optimisation off?
/OPT:NOICF is probably what we are looking for [1]:
"""
/OPT:ICF can result in the same address being assigned to different functions or read only data members (const variables compiled with /Gy). So, /OPT:ICF can break a program that depends on the address of functions or read-only data members being different. See /Gy (Enable Function-Level Linking) for more information.
"""
Now it makes sense that this only crops up with the PGO builds -- those are the only ones where we link with /OPT:ICF.
Can someone try out this option? I would, but I don't have a Windows box handy.
