I'm seeing some odd behaviour that I hope someone can suggest a solution for:<br>

Recently, when I run my tool on my test file I get errors that I don't get if I run clang++ with equivalent options -<br>

I extracted the command line produced by the FixedCompilationDatabase and printed it with quotes for extra paranoia:<br>
<br>
'clang-tool' '-Wall' '-std=c++11' '-fcolor-diagnosticsoo' '/home/peter/Programming/llvm/<u></u>llvm/tools/clang/tools/extra/<u></u>quaff/dummy.cc'<br>
<br>
First thing to observe is that -fcolor-diagnosticsoo seems a bit weird. Second is that running clang++ -Wall -std=c++11 /home/peter/Programming/llvm/<u></u>llvm/tools/clang/tools/extra/<u></u>quaff/dummy.cc doesn't error.<br>
<br>
This is on a fedora box, if that makes a difference.<br>
