             Bug #: 11833
           Summary: recent build failure with spirit code
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs

Created attachment 7929
  --> http://llvm.org/bugs/attachment.cgi?id=7929
original source file to reproduce (requires boost trunk or release branch)

The attached file lit_char.cpp fails to build with boost release branch and

The strange thing is: with clang 3.0 it works, with g++-4.5 and g++-4.6 it

Preprocessing with g++ and feeding to clang trunk does not produce the bug.

Preprocessing with clang 3.0 and feeding to clang trunk repreoduces the bug.

The attached file lit_char.preprocessed_with_clang_3.0.cpp.bz2 does not require
boost sources to reproduce the bug.

Changing lit('!') to lit("!") fixes the problem, however as it works for other
compiler versions I suppose it is a bug nevertheless.

The attached file lit_char.preprocessed_with_clang_3.0.fixed.cpp.bz2 does not
show the buggy behavior but requires source change.
