           Summary: cross compiling gas for arm fails using gcc-4.5.2
                    where 4.5.1 worked
           Product: binutils
           Version: 2.21
            Status: NEW
          Severity: critical
          Priority: P2
         Component: gas
        AssignedTo: address@hidden
        ReportedBy: address@hidden


gcc-4.5.2 warns of two possible use-before-init cases that gcc-4.5.1 did not.
These warnings are elevated to errors which break building binutils.

I've seen this under binutils-2.21 and 2.21.1
