commit 65fb0f3877a3e176a1ec0bde37814247365c19c5
Author: Kohei Yoshida <kohei.yosh...@collabora.com>
Date:   Thu Mar 6 15:58:25 2014 -0500

    Let's not leak ScTokenArray when compiling formula & some naming convention.
    
    Names that begin with m_ are NOT to be used as local variables, and let's 
not
    use a name that's identical to the name of a STL container.
