Parent is right.
The software product I work on also used PGO at one point. Our software is roughly 2-3 million lines of C++ code, and links with 40-50 external libraries. Under Window XP, VS2008 could not link our product with PGO turned on.
Before you complain about the bloat of FF, please understand that PGO uses many many times more memory than just compiling a regular release build. This is a Visual Studio linker problem, not FF problem.
