Hm. Maybe gcov/lcov needs to be teached about <built-in>? It may be that gcov prints that for built-in symbols. Lcov shouldn't try to open a file to get info about it. But I'm not certain, and reporting it to lcov seems like the right thing. lcov already groks this, just not sure why it cuts of the first char. in the file name. I'll poke the lcov people about it.
