Valgrind errors on regex! macro usage

[KokaKiwi]

Using regex! macro on Rust program cause Valgrind output many errors:

https://gist.github.com/KokaKiwi/11559159 (I don't paste it here because Valgrind output a lot of errors)

My rustc version:

sh-4.3$ rustc --version
rustc 0.11-pre-nightly (abdacec 2014-05-04 23:16:40 -0700)
host: x86_64-unknown-linux-gnu

Just update the issue because I found some memory leaks on regex! example shown on regex crate documentation.
Actually, it seems to happen with named captures, but I'm not sure.
Here a gist I made with valgrind output: https://gist.github.com/KokaKiwi/86a3ca97dff3bc7133d0

I just updated the issue instead of creating a new one as it seems to me to be related (as it speaks about both regex and valgrind)
