At fedora17, when try to install benchmark (such as: phoronix-test-suite install compress-lzma), It forked lots of processes to check g++ version, and then failed to install. But if we build the compress-lzma from source package, it works well. Is there someone meet the same issue or know the root cause? Thanks!
