I can also reproduce that on my F10 box; and after much poking around
and staring at regexps, I verified that the C and perl versions use the
exact same regexps internally, but split the input differently - augtool
correctly notices that the first * in 'lns' is not matched with your
small example, but the second is. Running under perl, the first '*' is
matched, and trouble ensues.

It seems it's a locale problem - if I run the perl test with LANG=C in
the environment, it produces the same result as the Perl version, but if
I run with LANG=en_US, I get the results you described.

It's not clear to me what causes the different behaviors; it seems Perl
is doing something with locale setup beyond what glibc does, otherwise
augtool should produce the same strange result with LANG=en_US, but it
doesn't.
