          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs

If LLVM is configured with --enable-optimization --enable-assertions and
built with gcc-4.2/g++-4.2 on x86-32 linux, then the llvm-gcc build fails
(see below).  This does not occur if gcc-4.3 or gcc-4.4 is used.
