Yes, you added USE="profile", [- ] profile - Adds support for software performance analysis (will likely vary from ebuild to ebuild) Which adds -pg as expected to CFLAGS, and of course you can't use optimizations when profiling.
reopening to change status
added a filter-flags for -fomit-frame-pointer if someone else mistakenly enables USE=profile thanks
