invalid conversion from ‘char’ to ‘const char*’ [-fpermissive]
   StringRef Msg = StringRef(Message).ltrim(' ');

                                               ^
Environment:

Ubuntu 15.10 (installed today)
gcc version 5.2.1 20151010 (Ubuntu 5.2.1-22ubuntu2)
Using git repository cloned today from github mirror
Using build instructions here <a href="http://clang.llvm.org/get_started.html">http://clang.llvm.org/get_started.html</a>
(except not using subversion, using git from mirror.)

My analysis is that ltrim(' ') should be " "

I guess that I should use -fpermissive somewhere.</pre>
