             Bug #: 11913
           Summary: error in backend: Cannot select: 0x9fcdbe8: f80 =
                    ConstantFP<APFloat()> [ID=12]
           Product: clang
           Version: 2.9
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs

The full error message in the listing is:

APInt(80b, 302240678275694148452352u 302240678275694148452352s)fatal error:
error in backend: Cannot select: 0x9fcdbe8: f80 = ConstantFP<APFloat()> [ID=12]

I believe it is involved with floating-point, _Bool, and *= operator.
This is C99 code being compiled with 2.9-6
