Hi Paul,
At first I thought "ok, either way." But then I found that after your change,
our pcre-invalid-utf8-input hangs. That happens because the following
infloops (stuck in pcre_exec) on a CentOS6 system:
printf 'j\202j\nj\nk\202\n' > in; LC_ALL=en_US.utf8 src/grep -P 'k$' in
That binary was linked with the libpcre from this package:
pcre-7.8-4.el6.x86_64
