[cfe-dev] Unused variable in lib/AST/Expr.cpp -- a bug?

[Dmitri Gribenko]

Hi,

I have found an unused variable (see below).  I am not familiar with
this code and I am not sure that removing it is the correct fix.

     Lexer TheLexer(SM.getLocForStartOfFile(LocInfo.first), Features,
                    Buffer.begin(), StrData, Buffer.end());
