[cfe-dev] Tool oddity

[Peter Stirling]

Hi,

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

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 -

I extracted the command line produced by the FixedCompilationDatabase 
and printed it with quotes for extra paranoia:

'clang-tool' '-Wall' '-std=c++11' '-fcolor-diagnosticsoo' 
'/home/peter/Programming/llvm/llvm/tools/clang/tools/extra/quaff/dummy.cc'

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/llvm/tools/clang/tools/extra/quaff/dummy.cc 
doesn't error.

This is on a fedora box, if that makes a difference.
