<pre>I found this fuzzing various inputs and command line options to clang-format
so, while I expect that this is an unlikely combination of options to be used
in practice, it shouldn't crash.
In this case 1.cpp just seems to have to not be empty. I'm using a file
containing only the character 'a'. My command line is:
$ clang-format.exe "--style={UseTab: ForIndentation, TabWidth: 0}" 1.cpp
According to the stack dump it's crashing inside
clang::format::WhitespaceManager::appendIndentText()
Tested with r249542.</pre>
