I was testing "www-client/firefox-5.0-r2" with "pgo" use enabled: it compiles fine but the produced executable segfaults immediately. So i decided to enable the "debug" use but it doesn't complete the linking phase, as it is missing "gcov" symbols: "undefined reference to `__gcov_*`". P.S.: As i'm writing it's compiling with the debug use, without the pgo one. I also tried to emerge -e my whole @system and @world, without success. Reproducible: Always Steps to Reproduce: 1.
